Unfortunately this is simply WRONG although I"m sure that Kareem believes it. But it should be understood that his rhetoric adds more to the problem of Radical Islam than to the solution.
Here is why in a nutshell: The leaders and followers of ISIS and the like believe that The Koran and The Hadith are to be interpreted LITERALLY. Is that what the KKK did vis a vis Christianity and the Bible? I don't think so. Kareem is wrong. Way wrong.
The problem Kareem is ignoring is that the Imams read the The Koran and The Hadith and they teach Muslims what's in it. So beheadings, slavery, killing of non-believers and such are part of the curricula. Until this changes there are going to plenty of support for ISIS from within the Muslim community. But not from Kareem apparently.
What he should be doing is leading the effort to welcome the Imams into the 21st century and to give up their literal interpretation of their sacred documents. Right now I don't see much happening on that front. Without it there is going to be a big war. A very big war.
What’s amusing is that Kareem is appropriating a nearly 15-year old argument made by Conservatives following 9-11 to support the use of the terms Islamist and Islamism.
