Since we are on the topic on why people are discriminated, why are many forums upset about religions? Not all of them try to choke you with it. If I recall correctly, only mormons do so, but only in a very polite way. For example, they will come to your door once every year or so, depending, and ask if you would like to join. I do not see an issue.
Also edit: Yes, I also do understand some people do try to assault you to convert, but only ignorant and rude people typically. But why is it stereotyped to all people of any religion?
