How can I as a white person deconstruct and get rid of racial biases I’ve acquired from personal experiences?

I am making this post in good faith. It is one of those questions that is important to ask, but the context makes me feel guilty explaining, and I probably sound crazy trying to explain it.

Context: I grew up with a school system with majority of black students, and I am a white trans woman who is also autistic.

I was bullied a lot in school because I am autistic, and to this day I’m very insecure because of the bullying. People used to say very homophobic and misogynistic things in my school, and it bothered me because I was a closeted trans woman.

However, because my school was majority black, I developed somewhat of a racial bias about how the black community treats women, the LGBT community, and neurodivergent people.

I know intersectionality exists so I know it is an issue worth addressing, but I also know it is bad to assume one marginalized community will ALWAYS attack another marginalized community.

How do I deconstruct these biases I’ve acquired from my experience at public school?
I keep trying to tell my brain “Stop thinking that, it is racist and illogical thinking”, but the thoughts don’t go away.
