The words "homophobia, homophobe, etc" are highly misused words and are used like they have the same negative connotations as the words "stupid, idiot, retard" (all actionable).
Dumb is a perfect example of the same thing. Dumb just means a person is mute, but is highly misused today to mean something completely different.
Homophobia means a person is deathly afraid of homosexuality, but today is used by ignorant people to be a demeaning term just because a person disagrees.
I submit you make using the following words actionable just as any other insult, as they contribute nothing to the forums, incite arguments, and disrupt normal forum activity:
-Homophobe
-Homophobic
-Homophobia
