I need help !

Well, I would say yes, it is prejudice. However, considering you are in a religios school, that is not unexpected. It sounds like you were a little disrespectful too in your original declaration. People are very sensative about their beliefs,and often react quite violently when someone is disrespectful to them.I would say that although it is definately prejudical, when in a religious school, keep your viewpoint to yourself. A religious school is not really 'public', and it not a very good place to advertise your beliefs if they are not in line with the rest of the school.

Well, I will agree that venting yoru spleen is not reason to be discrimated against. I know it wasn't your choice, but you have to live with the fact you are at a religious school.If you realise that venting your spleen is going to cause problems with your fellow students, you can either vent your spleen, and deal with the reaction to it, or you can keep your mouth shut, and suffer in silence.It's not fair, but hey, life isn't fair.
