Those of us who identify as gay?

[Sammy777]

If I'm with a guy, I can promise to not be with another guy,
if I did end up with a woman as my primary relationship, I'd swear off other girls.

THAT is it right there! And why Bisexuals have the bad name we do.
I hate to say it, but in those two statements you sound like the poster child for all things bad about Bisexuals.

We can't be trusted.
We will (sooner or later) run off with someone of the opposite gender of our current partner because we simply "can't decide".
We are just fundamentally incapable of being faithful or staying in a monogamous relationship for any length of time.

Your statements above are the holy grail of reasons why (Most) Gay men and Lesbian women avoid Bisexuals like the plague.

And as far as LGBT rights and advancements go, its simple, first to get axed "For the greater good" is the T.
The second is the B. Because Bisexuals muck up the works. "Real" bisexuals are a myth and don't really exist anyways.
