That’s a great point and a pet peeve of mine. I get annoyed when I write about something homophobic somebody has done and then get an avalanche of responses about how that person must be secretly gay.
I want to say, that’s not how life works. If the only severely homophobic folks out there where secretly gay people, we’d have a lot less to worry about. Yes, closeted gay people are more likely than other people to have very negative attitudes toward LGBTQ people.
But they still only make up a very small fraction of people who have very negative attitudes toward LGBTQ people.
