homo - any of a genus (Homo) of hominids that includes modern humans (H. sapiens) and several extinct related species (as H. erectus and H. habilis) and
phobia - an exaggerated usually inexplicable and illogical fear of a particular object, class of objects, or situation
so you are scared of hominids, I know I am not.
Its more like homosexual-aversion, or perhaps "reality of homosexuality syndrome".
Or it is an objection on moral grounds to a lifestyle which I find unacceptable. But there is NO fear.
