That's because invariably that's the context they out themselves in. If they just said, I RL am a homophobe, without the "and I write slash" they'd get the same reaction. And there is the added annoyance of get-the-fuck-out-of-my-preferred-genre going on.

I am curious however if these real life homophobics write their slash as though it is fucked up or not. I'm a rapefic writer, but I write my rapefics as being a fucked up relationship. I'm not big into rape = love. I'm big into rape = something to be coped with, rationalized and overcome. In other words, even as I write this messed up relationship, I acknowledge that it is a messed up relationship. I wonder if these people do the same. I kind of suspect not -- and that would be a bit of hypocrisy.
