It depends on whether you believe the research:
“Research by US psychologists suggests that 80% of men who are homophobic have secret homosexual feelings. (Bigots are buggers)
In tests conducted by Prof. Henry E Adams of the University of Georgia, homophobic men who said they were exclusively heterosexual were shown gay sex videos.
Four out of five became sexually aroused by the homoerotic imagery, as recorded by a penile circumference measuring device – a plethysmograph.
Prof. Adams says his research shows that most homophobes “demonstrate significant sexual arousal to homosexual erotic stimuli”, suggesting that homophobia is a form of “latent homosexuality where persons are either unaware of or deny their homosexual urges”. (Bigots are buggers)” Source
