The video is full of ignorance and actually promotes white supremacy. If you get mad at people with European ancestry claiming "white" because they are not fully white, then you are just promoting the notion of a pure white race a.k.a white supremacy. No one goes through these hoops to kick people for claiming black that have obvious "other" ancestry because for all this fake black nationalism, there is no such thing as a black supremacist.
If black supremacy existed and the so called black race had any respect on its name, people like Ice T, Steph Curry, Heavy D, Sinbad, Keith Thurman, etcl, would be criticized for calling themselves black just like Rachel Dolezal. However, because of the special disrespect that the so called black race is subjected to and also an accomplice to, if Dolezal was even 10% black she might have gotten away with it. On the flip side, you can't be 10% white and call yourself white because both black people and white people will jump to defend the purity of the white race similar to what this video is trying to push.
