I understand what you mean, that in some specific situations hiring for a specific race can be a benefit, but in cases like that you can hire for something similar that is legal again here too. E.g. you could hire by experience with certain communities, for example. Or you can hire for "sympathy". "This person is personally a good fit to our company and the role". With that point you can hire whoever you want.
This is also the Achilles heel of the anti-discrimination laws, since the hiring manager can just say "The applicant's personality wasn't a good fit" to anyone they want to discriminate against.
And yes, I have personal experience with how racist and sexist some of my bosses have been so far.
In one company, my boss was directly excluding any applications by women for IT roles, because "they would distract the boys in the IT department". Even though all "the boys in the IT department" were in long-term relationships. (Btw, I also really hated it that he called us "the boys" even though we were all ~30).
