Christians today like George W. Bush? Invaded Iraq, invaded Afghanistan, the first went totally to hell because of his policy of not actually rebuilding the country properly, getting rid of the Iraqi army and police and creating a vacuum.
That's just one example. There are many examples. While the Christians don't always go and cause problems with guns and bombs, it's a choice never the less.
Islam has suffered in the last 200 years, and it's suffered within most people's memories.
You have Iraq (twice) and Afghanistan, plus Libya and that's only since 9/11. Plus the French in Mali and a few other former colonies. You have interference in many Muslim countries, Iran being an obvious example where there the US caused so many problems, Lebanon, and then you have the support of Israel which some has been legitimate and some of the actions of the Israelis simply hasn't.
