Your sources seem to be a tad right wing. As such, I'd like to see more or better confirmation that non-whites are, in fact, allowed an exemption.
The links to Cornell's own site is there.
If they are, I agree it seems daft, on the face of it. But if it is only one of a number of reasons that an exemption can be requested, it's not so bad.
Assuming it is true, my only caveat would be the usual one, that it is incorrect to lump this sort of racial discrimination in with other sorts and what is normally understood by the term racism.
ETA: I see that I may have jumped in without reading all the prior posts. It seems BIPOC students are allowed to request an exemption.
Whether or not you can request exemptions based on other reasons, it's still racial discrimination.
Under the 'religious' exemption explanation, it specifically rules out
"Philosophical, political, scientific, or sociological objections."
So, Cornell, in all her wisdom, has decided that
* If you think God wants you not to vaccinate, you may be exempted
* If you have paranoid fantasies that vaccinations are a government conspiracy to experiment on "Black bodies", and you are BIPOC, you may be exempted
* If you object to tying a tertiary education to having a mandatory flu vaccine, you can go straight to hell. That's an ideological objection and doesn't count.
