It talks about the experience black people with autism have. In particular, it talks about someone with a hyperfixation on deejaying and how the video author relates to those experiences. The video author has a hyperfixation on writing.
Two notable points that stuck with me:
Black autists may not get diagnosed, because they're less likely to visit psychologists for depression and such. As apparently the family of his put it: Mental health issues are for white people.
Autistic behavior quirks themselves got interpreted as white people behavior.
