Half a century ago?
Not relevant to instances that happened within the past 3 years.
And 50 years ago, Christianity was still Christianity. Nothing has changed about it, unless the Bible rewrote a few passages over the past few decades. People still did those things in the name of their religion.
My point is still that it's the interpretations and people themselves that are responsible, and not the religions. That's not an issue bound by time, which is why historical examples are still valid. I'm not arguing that bad things aren't happening in the name of Islam, but an entire religion isn't responsible for the actions of a few. I'm sure there's some Christians that would happily hang gays from a crane today, given the chance.
The same argument is supported by gun advocates: It's the shooters fault, not the gun's. A gun is safe when used properly, and dangerous when used by a psycho. A religion safe when read properly, and dangerous when interpreted by a psycho.
Point me to a verse in the new testament that calls for the genocide of a group.
Christianity holds the values of the old and new testament equal. Again, it's just interpretation and reading. Some individual churches or branches of Christianity support one over the other, but that's not a "base Christianity" thing. The new testament is certainly a lot less barbaric, but that doesn't erase the old testament.
