It's not discrimination when it's based on objective reality.
But I guess you are one of those who will call discrimination when someone doesn't make the cut because they weren't good enough, whether it is in sport performance or intellectual capacity or anything else for that matter.
We are still hearing about discrimination of women in STEM subjects when not only they have the same exact opportunities but we reworked a lot of the education system to accommodate them in preference.
We can never win with your type because there is no logic, it's all about the feelings and emotions that uncomfortable truths create.
And nice trying on the racist insult, I fundamentally don't think there is a superior race or whatever, just that there are objectively different genetic heritages that are better at some things (and vice versa). It's the same thing for women, men are not able to make other humans, that's an objective truth.
Either you take advantage of that and assign different things to do depending on actual relative strength of peoples or you put your head in the sand, makes everyone go through meaningless competition that bring about the same results, just less efficiently and with way more casualties than necessary.
People are complementary, you can't have the smart ones doing masonry while the strong ones doing architecture, that's just stupidly inefficient and a sure way of creating problems in the long run...
And to be clear, I strongly believe in the equality of opportunities as well as equality in laws but that doesn't mean you have to engineer a whole system against "discriminations"; it won't work no matter how much you believe.
