I dislike to come across as overly sensitive, but I dislike how clinical sounding "homosexual" is. Just say gay people or LGBT. It isn't a condition. The DSM was wrong for a long period of time.
To be fair, I think it can be difficult to appreciate how it sounds if you aren't LGBT. If you're straight, you haven't been exposed to being demoralized because of your sexual orientation.
I understand the perfectly valid scientific use of it-- I'm just saying that sometimes people weaponize it. When you come across anti-gay rhetoric, it almost never uses the word 'gay'. It has phrases like "the homosexual agenda". The wording is specifically chosen to imply the group is lesser than others.
I’m sorry you feel that way, but “gay” sounds more offensive to me (e.g. “the gays” or “that’s gay”) and, ironically, euphemistic. LGBTQ sounds clinical (it’s an abbreviation!) and only half the letters relevant here.
Homosexuality is the most precise word (literally same-sexuality) to denote LG and DSM is hardly the originator of the word (the DSM was, is, and always will be, a mess. But that’s another issue).
Scientific terms are not value judgements.
Don't worry about how you come across, worry about how you are.
