I would deny it. Anonymity is a way to say what you really want to say without having to worry about the consenquences. Many people seem to think of it as a way to say something you know is wrong and because you dont want everyone to know that you believe such things you choose to remain anonymiss, but this isnt true. Just because you would be looked at as different for say something that doesnt mean what your saying is wrong.
People need to learn that what you believe is not necessarily the truth and to listen to other peoples opinions. You dont need to agree with it just learn to listen without yelling and bashing people for thier beliefs.
