Being straight is like being in gryffindor: all the main characters are always gryffindor, there’s tons of merch for gryffindor, and no one’s gonna give you shit for being in gryffindor.
Being gay is like being in slytherin: everyone has heard of it, but the merch is few and far between so you have to really want it. The only slytherin characters are secondary and morally gray. Some people think you are evil.
Being bisexual is like being in ravenclaw: there is no merch. there are no major ravenclaw characters. people definitely try to lump it in with either gryffindor or slytherin, and there are a few weird stereotypes.
