I feel that strongly-stated racism, bigotry etc can be dangerous in that they incite others to subscribe to the same mindset. Inciting hatred for race, sexuality etc is (as I understand it) a crime here in UK. One can have private views, which as has been said here, everyone has to some extent, but one should refrain from proclaiming them. I can see how this could be seen as censorship, but we live in society, and our words/actions have consequences. A bigoted standpoint causes pain, fear and resentment, and encourages the bullies among us to join up and attack. This can't be good for the cohesion or stability of society as a whole.
