For years I've had straight friends and gay friends tell me to choose one and to stick with it. My family and straight so called friends often tell me to make the right decision, as if I have a choice. My gay friends tell me to just choose guys so I can be a "real" gay like them.
In my case I'm sexually attracted to both males and females equally. Just because someone prefers only one of them, doesn't mean they are attracted to them more than I am. Aside from that, sexual attraction is beside my point. For me, love has much more complexity to it than the concept of gender preference and I don't choose who I fall in love with.
Bisexuals experience discrimination outside of AND within the LGBT community for not being gay or queer enough. I get not only disgusted looks from homophobic people when I publicly hold my partner's hand, but confused remarks from people who are strictly homosexual. I wish I would hear statements like "I'm gayer than you" and "you're not gay" less often. No one is gayer than me or anyone else in the LGBT community. It truly is a diminishing statement and it belittles the unique, and very real experiences bisexuals undergo, and contributes to bierasure in the LGBT community.
Homosexuality means attraction to the same gender, not "strict attraction to the same gender". The term gay used outside of the lgbt community often has negative connotations associated with it. However, it has an inclusive feature to it when members of the lgbt community use it with each other.
Anyone can identify as whatever they want to and no one has the authority to label you as more or less of something. Yes, I'm bisexual, but I'm just as gay.
