If you wish to discuss how you were moderated, then you should take it up with support. You can open a ticket by going to http://support.warframe.com - as there is nothing we can do here to help you appeal said ban.

With that said, I would like to clarify that moderation is very contextual. Politics and Religious discussion in chat very, very rarely comes from a place of meaningful discussion, and often these discussions break down quickly. If there is any discussion that targets another player or their beliefs (be they political or religious) then that is a violation of the rules. If you see instances of such discussion where a moderator may have missed such a comment, then you should use the in-game report feature.
