I honestly hate how bisexuals like myself are stereotyped as greedy, slutty, or confused. Or, posing as a bisexual just for sex or to please men. These statements are not true in regards to every bisexual, however, I bet you there are bisexuals out there that fall under a few if not ALL of these stereotypes. Personally, I am attracted romantically and sexually to both guys and girls; more so for guys.
I feel like we shouldn't bash a human being for their sexuality without knowing them personally, especially if members of the LGBT are the ones doing most of the harassment. If anyone should understand sexual discrimination it's be them! Pessimistic much? I think so.
Just leave people to be who they are and don't be quick to place a fellow human under a stereotype as soon as the words "I'm a bisexual" leave their tongues. Find your humanity.
