> If I say to them, "I will give you food, on the condition that I can punch you in the face", and they decline to be punched in the face, do you really believe "nothing wrong has happened"? That I, applying an unethical condition, did nothing wrong?

Yes, of course nothing wrong has happened. The other party decided that the food was not worth a punch in the face. The other party is no worse off than if you had made no offer. The other party is no worse off than if you had responded to "may I have some food please" with "no".

Downthread:

> It is routine and unproblematic for laws to exist that prohibit "you can't enter this bar if you're black" or "I won't hire you because you're a woman".

This is completely irrelevant. "I will give you food, on the condition that you change your immutable characteristics" is incoherent. "You can't enter the country because you didn't submit to this violation of your privacy" is a) targeted at someone who definitionally doesn't have those constitutional protections in the US and b) not an expression of any kind of identity-group prejudice.
