If Islam is like American-style Christianity, its followers actively ignore the words of their own prophet so they can do whatever atrocious shit they wanted to do anyway.
For Christianity, that means hating gays, subjugating minorities, and living a selfish, materialistic life while judging others.
Not only is there no biblical basis for those things, the RED words in the bible point the exactly opposite direction.
The Bible is very vague on whether you should still hate gays, have slaves, stone people, etc... Pretending that
Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them.
obviously means the old law can be ignored is moderate apologetics. All the Abrahamic religions have plenty of fire and brimstone, and killing in the name of God. Ignoring that is just as much an act of cherry-picking as is ignoring the more love and tolerance passages. The fact that it takes a "bible/koran scholar" to make a plausible argument other than "just ignore the old stuff" is problematic at best. Hell, the Bible ends with Revelations, which is seriously lacking in "turn the other cheek" and "love thy neighbor."
I could be totally wrong, but I'm pretty confident in this. The Bible is easy to use to justify misogyny, hating gays, having slaves, etc... My understanding is that the Koran is more so. Maybe the people doing that are "reading it wrong," but the fact that these "holy books" are so easily misinterpreted makes it hard to say that Christian/Muslim fundamentalists are not following the religion. They are doing what the books say to do.
Dear God, next time you inspire a holy book please leave out "allegories" that seem to promote killing, enslaving, stoning, beheading and burning people at the stake for victimless crimes. Someone might think you meant it. Actually, please stop being a lazy bastard that outsources all killing, enslaving, stoning, beheading and burning people at the stake do do it yourself.
