I don't have any specific numbers in front of me, but I think you would find that a majority of the gay community has had sex with someone of the opposite sex.
I think a lot of confusion is from this difference in outlook. I consider my sexuality to be a function of what sexes I presently find sexually attractive. You seem to be seeing it as a function of who you have ever had sex with, or something at least along those lines.
Gay people report that they do not find the opposite sex attractive. Some of them even report that while they had sex with members of the opposite sex, they weren't really turned on. That they were essentially 'faking it'. These people I would not classify as bisexual, even though their lifetime sexual experience is bisexual in nature. There are also gay people who have never had gay sex, at least not anal intercourse.
Likewise, a person who reports to me that they only find guys attractive, but they've only ever been with a woman and it felt unpleasant - I'd categorize as gay, even though his present sexual experience is heterosexual in nature.
The test as to which of us is right should be down to how the words are actually used.
If I introduced myself as being gay, what would most people think?
I submit that most people would infer from this that I did not find women sexually attractive and that I only go for other guys. The word gay, used in this context, and in common use, clearly refers to an exclusivity. By referring to myself as gay, people will get the wrong impression, meaning I have failed to communicate properly, which means the word is an inappropriate one to use in this case.
But yes, if I am with a guy, that is a homosexual coupling. That doesn't mean we are both necessarily homosexual. In fact, we might both be straight and deluded/confused/drunk/on psychotropics/experimenting/students.
If I marry a guy, that is a gay marriage.
And gay rights are the important ones because the straight rights are already taken care of to a sufficient degree.
It isn't that you are calling bisexuals 'gay' that is the central problem though, unnecessarily confusing as it is. It is that you characterised them all as attention craving self involved gays. There are words used to describe the action of taking a small sample of personal experiences and using that to draw inferences about the characteristics of the whole group, and they are words I'm led to believe you wouldn't want yourself labelled with. I appreciate that it was 'off the cuff', and probably a bit of fun - but then you continued the position beyond the confines of the joke in further discussions with me.
Can you at least understand how a person who is bisexual, or indeed any person of any group, may be upset when such negative stereotypes are presented about them?
Can I also request you try a civil tone? No giant capitals everywhere, use italics for emphasis instead, no condescension, no needling, goading or 'monkey poking' or any other trolling. That'd be super.
