"Bisexual doesn't necessarily mean we are only attracted to binary people. "

Certainly!!!
I've been asked questions about bisexuality, and I've heard it all, including things like "If bisexuality exists, then there are only two genders" one too many times, and you know what? I'm tired of having my sexuality used as a foundation for ignorant comments, you know?
So yeah, you're absolutely right and I'm so so so so happy you made that comment!
Bisexual means we are attracted to two genders, that's what bi means!
