The problem with this video is that the voice-over unsurprisingly lumps all of Christianity into one collective. You gotta love youtube. It'd be like me using Mao, Pol Pot, Hitler, the triangle slave trade as proof that science is wrong and immoral and therefore should be stopped.
With that said, the problem with fundamental christians is that they seem to have the loudest voice in the media for some reason. Probably because they have the most insane bat shit opinions about life. In many ways, fundamentalism should not even be considered Christianity. But that's another conversation for another day. Many followers blindly accept this as the true religion that has been around forever, when in reality, it's about 125 years old.
But yeah, these guys in this video put the 'mental' in Fundamentalist and the the British voice-over guy is a misleading piece of shit.
