And Christianity doesn't have any terrorist (no, I forgot, we are supposed to call them "abortion clinic bombers" or stick to specific names but never lump or label them as terrorist)? The Bible prescribes horrible punishments that would be illegal today and considered horrendous, barbarous, and inhumane by the standards of most today, but we are still going to ignore that and apply "stone-age" to Islam? We are talking about a group that amounts to less than 10% of its total global adherents that we need to be scared of, yet in America we are killing ourselves off with murder and traffic incidents much faster than any of these terrorists are.
Now if you want to go to some African or Middle Eastern nations, then it is a very different story, but do not forget that Christians are mercilessly butchering Muslims just as Muslims are slaughtering Christians without remorse.
