A while back there was a Paper written about the causes of homophobia. They hooked up homophobic and non homophobic men who reported themselves to be exclusively heterosexual to penile plethysmograph devices, which measure even the slightest of erections, and showed them gay, straight, and lesbian porn. Both populations where aroused by the straight and lesbian porn, but only the homophobic men showed what the paper refers to as "significant arousal" when they saw gay men having sex. This is kind of an old study, but I think you might find the results interesting. Something about knowing that all those people who make fun of gay people really just hate themselves is oddly satisfying to me.
I haven't read that report, but I have read one that was the same experiment with the same results. What you must realise is their definition of homophobia. They defined it as being uncomfortable about homosexuality. Meaning they wouldn't like to watch gay people kiss, hold hands or anything like that. Genuine homoPHOBIA rather than just being a cunt It does not mention anyone who is bigoted towards the GLBT community, eg strict religious people For that reason, I would come into the homophobic category, even though I am a supporter of gay rights
