The definition is "The fear of homosexuality."
But I beg to differ.
I think the real definition is, "The fear that your insecure with your own sexuality that you have to hate on other people's life, so people don't suspect anything, so hating is an easier way to be more "secure" with your true sexuality identity."
Cause honestly, have you met a gay man/woman who is hetereophobic?
It's just two people in love, if you honestly are that INSECURE with your sexuality, maybe you need to go get some therapy and understand who you are. I can understand if you are annoyed by the gay community, but hating them just because they are "gay"?
If you hate gay people, it just proves that obviously you are in denial with something in life, cause there is nothing to be afraid of if you are truely straight
