Excellent 180 degree perspective!
You might say that a man who has a problem with gay men is a bully, and that’s bad enough, but I think you nail it more firmly than that. Men who have problems with gay men probably have problems valuing women as fully equal to them.
Not good partner material.
(Not to overly generalize. Some men are likely homophobic for other reasons, including loathing their own latent same-sex attraction. People are complicated, eh?)
