I think the problem you're having is that you're interpreting "phobia" as "fear" - arachnophobia = fear of spiders; acrophobia = fear of heights.
The Greek word "Phobia" translates to "fear", but this meaning has long since been corrupted in the English language. Its English meaning is closer to "aversion".
"Hydrophobia" doesn't mean "fear of water" - it refers to a property of certain chemicals. A chemical that repels water is described as "hydrophobic".
"Photophobia" doesn't mean "fear of light". Ever have your eyes dilated and walk outside in the daylight? You likely experienced photophobia.
"Phonophobia" and "Osmophobia" have similar meanings for sound and smell, respectively.
As it is popularly used, "Homophobia" refers to an aversion to homosexuality. Nothing more, nothing less.
WITH THAT SAID, your argument suggested that there was no such thing as "an irrational fear of homosexuals". Seeing as how nobody else in the thread had even referred to such a concept (all other uses of "homophobia" described the simple aversion to homosexuality, not a pathological condition), it's your obligation to prove your point, not mine to disprove it.
