Reddit bisexual vs gay

Having to justify that one who is bisexual isn’t attention seeking and then be asked invasive questions about my sexual relationship history to try and judge if I’m “gay” enough.
I've seen plenty of bi men go from being confused about gay men not wanting to be with women, to flat out calling them close-minded and bigots for being gay. A lot of bi men, because they're bi, cannot comprehend some nuances of homosexuality, so, again, there are differences there.
