Your beliefs as expressed (the sum of) are highly contradictory and conflicting.
I'm surprised you can't see it.
Here's a hint: most/all "affirmative action" schemes are drawn along the lines of race and sex.
You stated that these schemes do not disadvantage the other races/sexes that don't benefit.
When asked if you agreed with equality of outcome you went off on a tangent about "diversity". Then said that "white people are diverse" but that didn't stop the need for "more diversity". You used this as a justification of "affirmative action" schemes. Run along the lines of race and sex.
Hence you must believe that skin colour determines many things about a person, such that having a workforce with many different skin colours guarantees a workforce with a "more diverse" set of ideas/experiences.
None of what you said is the slightest bit convincing, and as a package the sum total of what you said barely makes any sense as a coherent position. *Unless* you believe that people with different skin colour can't be similar. Either in upbringing, experience, or equality of opportunity.
Allow me to spell it out for you.
On the whole, I agree with the report and its position that many outcome differences can be explained by factors other than current institutional or structural racism.
That doesn't mean we should take no action to try to address or manage the impact of both the causes and effects of these disparities.
I reject the notion that the simple existence of targeted or, if you prefer, discriminatory, programs or rules for specific things results in a net disadvantage for those not part of the target group. It's simplistic nonsense.
You appear to demand I support one extreme or the other, either an absolute acceptance of structural racism and a demand for equality of outcome, or an absolute rejection of any claim of racism and a demand for any form of consideration for disadvantage be removed. I reject both, and the false dichotomy it creates.
