I'm with the teacher
These days, to the younger members of society, gay means "lame", "crap" and similar. They also know it means homosexual and even that it used to mean happy but language evolves and the current evolution of "gay" is lame and crappy.
I think the homosexualists as involved here have a problem because, in general, the vast majority of people have no problem at all with someone else being homosexual, or with homosexuality itself*
This means there is a sudden black hole in victim status and a reduction in need for LGBT spokespeople and anti-homophobia crusaders. So they need to scrape the barrel looking for victimisation, rather than moving on and being happy that homophobia today is nothing compared to what it was even 20 years ago.
*Sure some right-wing, nutjob or religiously stupid groups have a problem with homosexuality but even most of them now take the view of "hate the sin but love** the sinner".
**Not like that, stop sniggering at the back there.
