Sexualism / sexualist

Discovered something very interesting in wikipedia today. I realised that my use of heterosexist is wrong/flawed. Below is a snippet of heterosexism.

Heterosexism has been suggested as alternative to homophobia, in part because it uses a parallel structure to sexism or racism. This parallel approach, however, is logically flawed, as the literal meaning of the word would therefore be "a belief that one type of heterosexuality is inherently 'better' than another type of heterosexuality" (see the dictionary definition of, for example, racism). A true parallel construction can be found in the word sexualism.

So the word that can really replace homophobia is sexualism, which I presume would be the right word to used. I've always figured that homophobia is like a fear of GLTB people, which doesn't really mean the person hates us (personal view). So sexualist would be the word from now.
