//Same sex relationship is a moral issue. It is acceptable that people will have different opinions but all should respect the rights of others. The Holocaust is a factual matter not opinion, and those denying it should be called to account.//
This. You can disagree with same sex or mixed race couples if you wish, although if you state your opinion in a forum, others are also entitled to take a contrary view from you. Deny the holocaust, or try to argue that the Earth is flat, and you're flying in the face of truth and fact, and you shoulf be prepared to get run over by the logic bus.
