I've given up long ago. I tried to convert one of my friends in IRL, but it's hopeless. There's no way you can do it on a forum.

It seems as if though religion teaches people to believe what they are told first and if common sense contradicts what they were told then they, themselves must be wrong. So since dogma is defined deeper than thought for religious people, it is impossible for us to make them throw out their beliefs by making them think.

Just think about it, kids are taken to church when they're only a couple years old, before they can reason for themselves. So they are taught religion before they are taught reasoning.
