From what he says in the rest of the post, I think he means that being gay is something you can hide as it's not visible like being black. And due to the negativity of phrases like "That's so gay" and ridiculous commercials like this one, young people are more likely to hide it and think there's something wrong with them.Homosexuality is, as far as I know, genetically applied as well. It's just that there's some people who believe it is a choice, and homosexuals who try not to be homosexual. Both of those are inherently wrong though.
Do I see anything wrong with uses profane words? Not really. But using slurs against a group that is currently not accepted as equal for unknown reason in the most powerful nation in the world isn't acceptable yet. Using (BAN ME PLEASE) now is used like how Hip said (at least around where I am). Using gay and (BAN ME PLEASE) isn't. It's like using the word (BAN ME PLEASE) in the 1950s. We aren't at the same place with these two issues.
