Many years ago and it always irritated me. Phobic is an irrational fear of something. No one is afraid of these people. Maybe we should have been. They have corrupted the culture almost beyond recognition.
“Homo” means “self.” Phobic means “fear of.” I am not afraid of myself therefore I am not homophobic.
The campaign to make people not fear the real horrors they can inflict upon a society started in earnest in the 90s.
It was a very successful campaign.
