There is no proof she is a man. You can dislike her without making her into something she is not: a man. If you don't like her music, that's fine. If you don't like her message, that's fine. If you think she promotes values that are contrary to yours, that's fine. But let's not make her into the proverbial anti-Christ, demonizing every last bit of her every essence. There are enough people in the world that TRULY deserve that kind of contempt/discrimination.
I will say in Dr. Brennan's defense though, if she is donning something that makes her look like she has a penis, then she is striking a new low.
