Most gay men I've encountered either don't believe that it's possible for a man to be bisexual, or go out of their way to treat and refer to men that identify as bisexual as gay.
Is it because they have internalized homophobia themselves and are jealous that bisexuals have an attraction to women (bringing them closer to "normalcy" in society's eyes)? I'm very curious.

Bisexuality is just a stop on the train to Gay-Town.

The words I live by.

To be fair, society as a whole erases male bisexuality, while turning female bisexuality into something that girls do just to turn on guys.

Because lots of white gay men hate everyone who isn't a white gay man.

And even then they'll attack white gay men who aren't attractive to them, or are trans, or act feminine etc.

Not that I'm saying that it's only white gay men who erase bisexuality of course, but in this case it's part of a larger pattern.

Bisexuality is very real. I don't understand when other people who are discriminated against tell people that how they feel is not valid. How can a gay person tell a bisexual person that they should not feel that way? I cannot comprehend it.

You all just see ignorant comments on this forum and assume it's white gay men when straight girls, straight guys, gays of color, etc. are doing the EXACT same thing. I know it's become trendy to hate white gays and white gays are no longer protected by political correctness like other gays, but I'm sick of it.

Anyway, I don't try to erase male bisexuality, but I can admit to being a tad bit jealous of male bisexuals because they have the option to live a more normal life.
