There are significant cognitive and physical differences between different races that are THE main deciding factors in the successes and failures of members of those races in different arenas. The breakdown is something like 95% nature, 5% nurture. Nobody will admit or accept this, in spite of it being plain as day, because it’s an “offensive” concept. I also believe that research and empirical data confirming this is suppressed, though often tacitly.
That said, this calls for even more equality-supporting laws and behaviors like affirmative action.
