"White" supremacy is a fact. In every significant area of our society and culture, the greatest contributors happen to be "white." This is not to say that,
- There are no significant contributors from other demographics,
- "White" people are in any way superior to POC's, or
- "White" supremacy justifies any sort of discrimination or oppression of non-"white" people.
But "white" supremacy is just a fact. It doesn't hold anyone back from making their own contributions or accomplishments, regardless of gender or other demographic classification, but to deny it is just foolishness.
The CAUSE of "white" supremacy is mainly just numbers. OTOH, the REASON why Blacks and Hispanics remain sucking on the hind teat of the society economically, is a combination of numbers and culture. The proof of this is the success of Asians and jews. Both are "minorities," both are the victims of harmful discrimination, and yet they do fine. Blacks and Hispanics have a culture that disdains most of the characteristics that breed success. Not my fault. Not the result of racism. Mainly self-caused.
