I think that perhaps you are mistaken in your assessment of the current state of affairs in regard to world religion. Although there may have been a recent spike in Muslim extremism, if anything, most religions are much LESS extreme than they used to be.
For example, I am a Roman Catholic. You don't see Catholics launching crusades, burning people at the stake for blasphemy or holding inquisitions these days though.
Similarly, you don't see Jews stoning members for being adulterers, Fundamentalists going on witch hunts or the KKK riding around and lynching minorities.
Getting your information from TV and the Internet provides a very warped perspective of modern religion. Typically, news outlets are in the business of reporting BAD news. Thus, the only coverage you are likely to see on religion is when some lone nutcase does something to draw attention to themselves. You never see the story of the 99.9% of the faithful who are not extremists. If you want a better perspective on the reality of today's religions, I would suggest going to the services at 100 different churches in your own community (most do not mind having guests sit in on services) and then report back on how many of them turned out to be preaching extremist views. I think you would find that there is no more extremism in religion than you would find in comparison to any other groups these days.
