I've said before, that 'homophobia' means "supporting diversity and multiculturalism."
Those who support `diversity' and `multiculturalism' would hesitate, even the bravest among them, to refer to those who disagreed with their agenda as
`Heterophobes'.
After all, `heterophobes' might just refer to
Homosexuals who hate straight people (whom they often refer to as `breeders', a term of ultimate contempt among gays).
