If you’re attracted to both genders, then you’re bi whether you act on it or not. I think it’s more than just being an ally. People are recognising their sexuality more and not afraid to express it. The Kinsey studies would show it’s more of a spectrum than a binary. I think some older people in the lgbtqi community are less accepting of bisexuality as a concept, probably due to people using it as a deflection, or phase when exploring their sexuality historically. They might then choose not to express it due to intolerance, which led to people misunderstanding that bosexual people are just as valid. If you’re bisexual in a cos heterosexual relationship, you’re still bisexual, just like in the past gay people would live heterosexual lives. It didn’t make them straight. Being part of the lgbtqi community is not about having a shared experience of prejudice. The whole community activism purpose is to ensure that there is no prejudice in the future.
