Alrighty, guys, there is a majorly important issue here that I think you're all forgetting.
It is impossible to discriminate based on race, religion, sexual orientation, or any other similar thing on the internet unless you specifically say you are part of that race, religion, etc. My question is, how in hell did the server even KNOW you were a part of a specific religion, and then why did he kick you?
The reason is that I have seen, time and time again, people go through the following chain of faulty logic:
1. Person mentions he's part of a specific minority.
2. Person proceeds to be a complete asshole.
3. Person gets kicked from the server because he's being highly annoying.
4. Person complains that the server just hates him because he's racist.
That is just completely faulty logic, and honestly very, very absurd when you really think about it. I'm reminded of the classic GKWX2 "You just hate me cuz I'm black" retort which is so incredibly funny because I didn't even know his race at the time. I'm also reminded of the old SFGHQ troll, Wetflame, who used that 4-step chain of bad logic so many times as to get banned from SFGHQ for it.
I see no reason why you should even SAY your religion on an SRB2 netgame, and since it's impossible to tell after the fact whether this is my 4 step chain of faulty logic or actual discrimination, I'd say you need to lighten up and remember that this is just a game on the internet. If you don't talk about things people could discriminate about, there's no way that could possibly happen.
Now, if a server is asking, on join, what religion you are and kicking anyone of a religion he doesn't like, THAT is discrimination. However, just being banned while being publicly part of a specific religion is most likely not, and probably just you being kicked for another reason.
