@Lixa1603 it isn't really wrong since most people use it that way. but the definition would be that bi is when you're intrested in 2 or more gender and have a preference. for example I'm bi and I like man, woman and non-binary people but I have a preference to woman. that makes me bi. if I wouldn't have a preference that would make me pan. and if I would like all gender and have a preference that would make mi omni. but most people don't know about omni so a lot of omnisexual people just use bi
