I really don't see that as a special problem of the genre anymore. The slurs and put downs don't seem genuine to me in the literal sense; they really mean to hurt and offend people, but the people saying them don't really find gays disgusting, they just know that ****** is going to cut deeper than dummy. It's interesting that you brought up Earl; Frank Ocean's gay (or something), and as far as I saw the rest of Odd Future (and most of the rest of the hip hop community) was totally supportive when he came out.
