My dad told me I am not bisexual

I (13f) was having a arguement with my dad (41m) about trans people. It started when he started praising Ben Shapiro, and showing me a video of him. I was disgusted, I started saying how harmful these things were. He was talking about how trans women aren't real women, which is absolutely disgusting. I argued with him for a long time. Durning the arguement, he asked why I care so much. I told him it was because trans people deserve respect and rights no matter their gender, and I'm very protective of those in my community. He asked what I meant by "my community", and I came out to him as bisexual. He then told me I'm not bisexual because I've never done the deed. I was shocked and apalled. I know he's wrong but I can't get it out of my head.
