I have to say that when I was growing up, it was the other way around for me. The word gay was considered a pejorative, where homosexual was the politically correct term to use.Don't say: homosexual
Why? This clinical term from the early 20th century suggests that being lesbian or gay is all about sex and is somehow disordered. Furthermore, the term has been co-opted by the religious right, who use it as a weapon against gay and lesbian people.
Instead, use: lesbian (for people who identify as women) or gay (for people who identify as men)
So I'm questioning your demand that only certain words be used. What if a member of this group wants to use the word homosexual?
Again, I notice that here, something is being treated as an axiom, as something that cannot be denied. (Just so you know, I accept that sexuality isn't really a choice). I do have to say that this is dangerous, since it squelches any discussion of alternatives. What if one day, there's very strong evidence that sexuality IS a choice? Will you allow it to be called such then?Don't say: sexual preference
Why? This terminology implies that being non-heterosexual is a choice.
Instead, use: sexual orientation
So you know, I am not suggesting that we 'balance' things here (e.g. every non-choice post must be paired with a choice post).
I can probably understand your reasoning here - most such promotion of choice-sexuality is driven by religious bigotry and you don't want to allow that here. Fine. Then say that. Say that unproven bigoted responses that claim sexuality is a choice, backed up only by religious doctrine and no actual evidence, are unwelcome here. Don't just flat out ban it.
Another reason why I felt like posting this was because I am very uncomfortable when groups or people say I HAVE to use certain words, or there's a problem. It's to do with words being constantly declared non-PC, and new words and terms being introduced to replace them, only to have those words also being declared non-PC and so on and so on.
I never would have expected the word homosexual to be banned, but then again, I should have.
