Accepting that, you can of course debate what sorts of racism we should allow, and perhaps even encourage. I probably disagree with you, but that's just my opinion.
Observing a bias, quantifying it as best as possible, and deploying countermeasures in corresponding degree to reduce its impact, is not racism.
But if you believe anything which assigns admission/hiring/recruiting scores on any basis other than objectively-measured individual merit is "racist", you cannot plausibly be in favor of current hiring, recruiting or admissions practices, and have far larger fish to fry than the relatively small number of people whose admission/hiring is solely due to affirmative action.
In all seriousness: look up the ratio of "legacy" admits to, say, black students admitted at top colleges, and then remind yourself that "black" is not synonymous with "affirmative action admit", and then ponder which of "legacy" and "affirmative action" would cause the greatest overall change toward fairness if eliminated. Then focus your efforts accordingly.
An extravertedness bias in underclass culture is the main reason people why people don't get into coding, which is historically more something for introverts and a "nerd thing". It's still in peoples minds, nobody in High School wants to be like Steve Urkel, it's a vulnerabilty in certain circles.
This can only be changed by changing the image of coders within mainstream pop culture, which in turn is mainly influenced by lower class culture, especially Hip-Hop culture in the last decades.
And round and round and round we go! Everybody has a convenient finger to point at someone else who's responsible, and if all else fails blame the people discriminated against and say it's their fault for not doing more to overcome the discrimination.
It's not a race or gender thing, but class struggle, dysfunctional families and problems that are passed on through generations. If your social group is basically your family, you can't afford to not fit in. It's a parallel society with its own rules.
