How would you define "gay" in regards to "gay rights" or "gay marriage"?
I wouldn't. The word gay is not defined in terms of "rights". "gay marriage" is simply the marrying of two individuals of the same sex, irrespective of their own individual sexuality. There is, as far as I am aware, no test required to prove that one is gay before one is allowed to partake in gay marriage...
It's starting to become apparent that the people here who are really homophobic are the self described "bi"s who throw an absolute hissy fit if you dare to suggest they might be "gay".
I doubt it. I have often heard my gay friends speak of finally coming to terms that they were not bi, and were definitely gay; that they didn't have to pretend that they found women in any way sexually attractive. I found it fascinating myself how they would describe their revulsion to female genitalia as I would describe my revulsion to other males' genitalia.
