I swear these people think if they go on these "crusades" they garner points to get into heaven or something. 
That is true! That is why in real life and online I try to stay away from the topic of religion, people argue way to much about that subject and it strikes many nerves. I'm not religious but I do celebrate christmas, I guess I'm christian. *Shurgs*
No that this has to do with this particular case but you also see these kinds of jerks in literature, like in
To Kill A Mockingbird I can't remember exactly but these group of religious people tormented a lady that lived across the street from the main characters because she liked to garden and they said she'll go to ___ because of her hobby or whatever.
And don't forgot the Europeans enslaved the people who lived in Africa and destroyed their lives but thought they were doing good because they were converting some of them to Christianity. I hate history class because of all the missionaries you hear about that come from Europe...
Religion is way to delicate a subject, it is best to keep it to yourself and talk about it in a friendly manner and not put down others as you do.
Edit: Darn it was fake, oh well I still hold my opinions on how much people are jerks when it comes to religion
