Like with any religion or collection of people, there are those who simply react, generally out of insecurities and fear. And yes, they do so in such a way that they completely contradict themselves and their claimed "beliefs". Christianity like many religions hold a belief that clearly contradicts to a large degree any notion of tolerance or acceptance. The idea of hell and exclusivity for one religion's followers being allowed into heaven. This exclusivity brings out the nasty side of many religious people, leading people to cast judgement in contradiction to their teachings etc. etc. over and over again, ad nauseum. But of course they don't see it that way.
