So by banning these terms you're taking away words that the gay community uses to identify chosen roles within the culture? Got it. Nice work, A-Plussers. Everyone gets a trophy.
Not really - I saw no one there discussing banning "queen" or "queer" or "gay", just homosexual, homosexuality, male, female.
And to add to The Prestige's answer,... "It depends..."
Purely anecdotal, of course, but I've seen a closeted bear referred to as a "musty old queen". In casual conversation, especially mixed gay/straight, they'll often throw out any old term, largely as sarcasm. But if you're ever in a serious conversation with them, they will use the separate terminology. Butch has a meaning; as does bear; as does queen; as does twinkie; etc.... Hell, probably just to piss off A+, they'll also throw about "fag", "faggot" and "homo".
And that friend I mentioned who's a bit of an activist? He takes on the gay/bi community on using those sorts of terms because he's dead serious about it all and thinks they help ghetto-ize the gay/bi/trans community. He claims that most of his buddies agree when pushed for an answer, but mostly can't be bothered. I'd send him over to A+, but his details would probably break the database. He's a dyed in the wool Catholic Gay Activist.
ETA: faggot - - testing
I wasn't sure if it was a forbidden word, and I remember something from some forum where putting a forbidden word in quotation marks got you around the auto-censor, so wanted to test.
