The first thing we need to establish is who this fellow is and whether he has the right to make sweeping comments about Islam. Grand Ayatollah Ahmed al Hassani al Baghdadi is a famous Iraqi scholar and cleric. Unlike their Iranian counterparts, the Iraqi Ayatollahs do not exercise direct control over the secular government. However, considering the current situation in Iraq, the Iraqi Ayatollahs probably do have more real world influence than the government does. When a tribal leader or a local politician has a question about the religious nature of a decision they must make, that leader either consults one of the Ayatollahs directly or refers to one of their publications. In a country such as Iran, the Ayatollahs are the government because the secular government operates at the mercy of the Ayatollahs. The Ayatollahs are the most important leaders at the top of the theocratic hierarchy in Shia Islam. They are the experts everyone turns to when they need answers about how Islam applies to life in the modern world. It is true that outside of Iran the ability of each nation's Ayatollahs to enforce their decisions becomes somewhat limited. However, it is equally important to note that even in countries like Jordan or Saudi Arabia many political and legislative decisions are designed to be as inoffensive as possible to the Shia leadership because if the Ayatollahs are not satisfied, they can and will inspire outbreaks of Shia or Wahhabi violence by issuing one or more "fatwa", which is a call to arms for the most conservative Muslim faithful.
Sunni Muslims are less inclined to dogmatically follow the dictates of their leaders. Most of the "modern liberal Muslims" President Obama likes to refer to are Sunni Muslims. They play modern music, wear modern clothes, the women work alongside the men, their children are raised in secular schools and taught to have secular goals. Although there are some exceptions, the majority of violent Islamic radicals responsible for modern terrorism are Shia, not Sunni. Those Sunni Muslims who do wind up terrorists are often from the Wahhabi subset, which parallels Shia in its propensity for extreme conservatism. Some terrorists who are raised in the West might not even realize which school of Islam their parents have taught them to follow since Sunni Islam accounts for the vast majority of Muslim adherents. In many cases, although not in all cases, when a Muslim raised in the West is "radicalized" what has happened is the children of a Sunni family have discovered the writings of either Shia Ayatollahs, Wahhabi evangelists, or both. However, even in a predominately Sunni country such as Saudi Arabia, many of the stricter Shia Ayatollah theologies are the deciding factor in legal circles because the country uses Shari'a as the basis for their national legal system rather than English common law or German case law. Although English common law and German case law are compatible with each other in many areas and are the basis of most modern legal systems in the West, they are both completely incompatible with the theocratic precepts of Shari'a. Western scholars neither like to recognize it nor admit it, but the writings of Karl Marx and Frederick Engels have so many parallels with Shari'a it is entirely possible that Shari'a was the inspirational basis for communism. Impossible to prove, of course, but the number of parallels is truly uncanny, especially in the treatment of the poor and the assumption that violent overthrow is necessary to impose enlightened rule on self-centered humans.
The rise of ISIS, for example, was expedited and made possible because Nouri Al-Maliki, a Shia Muslim, violated the mandate given to him by the American government. As soon as the United States removed their military from Iraq, Al-Maliki consolidated his power by driving out Sunni military officers and government bureaucrats. Many of the Iraqi Army divisions that walked off as ISIS advanced, leaving behind advanced American weapons and armor, were Sunni divisions whose commanders Al-Maliki had fired and replaced with Shia officers. Given the choice between political isolation in Iraq and political power with ISIS, they naturally chose ISIS. As a result, the ragtag and undisciplined mixed band of Shia and Wahhabi terrorists who had broken away from Al Qaeda gained a multitude of experienced, competent Sunni commanders, bureaucrats, and social leaders. Faced with a common enemy, the Shia and Sunni naturally fall into this sort of arrangement with the Shia guiding the passion of the collective and the Sunni providing the realism that keeps it functional.

If the West submits to the demands of terrorists it will have far more impact on our daily lives than a few changes in how we do business or what our children learn in school. Submission to Islam means global imposition of Shari'a. Western law, with its emphasis on individual rights and personal responsibility, will be replaced with jurisprudence defined by the Shia Ayatollahs which is then enforced by strong arm Shia and Wahhabi moral police. In Shia Islam the Ayatollahs are far more than legal scholars; they are the hand of Allah on Earth and the only ones enlightened enough to make decisions about how people should go about their lives. Scientific pursuits would be grudgingly entrusted to Sunni researchers, but the Shia Ayatollahs would decide which avenues of research were "in line with Allah's plan for humanity" and which were "the realm of Iblis that can only bring sorrow to the people of Allah". Shia Ayatollahs are recognized throughout Islam as the only source of divine wisdom on Earth. Pursuit of any field of study not marked out as acceptable by them is accompanied with either deep feelings of guilt or elaborate self-justifications. A Muslim forensic pathologist, for example, might enjoy their work immensely and believe it is important but their family and friends would be relentless in their ridicule of examining dead bodies as a career choice.
According to the Pew Research Center, Islam is the fastest growing religion in the world. (See, The Future of World Religions) Whether anyone likes it or not, whether ISIS is defeated or not, by 2050 it is entirely possible that Islam will control our world. Unless something changes and changes fast, our children and grandchildren will live under an Islamic Caliphate governed by Shari'a that spans the entire globe. It is less than one generation away. Either you are comfortable with this idea or you are not. It seems to me that if you are, you have not fully grasped just how dramatically different life would be under global Shari'a. This is more than just brutal punishments for crime and women being forbidden from driving. Global Shari'a means the number of children you are allowed to have, where you are allowed to live, what kind of work you are allowed to do, and the upper limit of your earning potential would all be dictated by Shia Ayatollahs and enforced by Sunni bureaucracies. Space exploration will completely cease, or at the absolute best, be limited to unmanned orbital satellites which make it easier for the government to monitor and control the population to insure everyone is conforming to "the Prophet's divine guidelines for happiness and prosperity of all".
If you think greedy capitalists are harsh taskmasters, just wait until you are forced to live under the dictates of the Ayatollahs!
