Sorry, I don't know any LLMs that would argue politics without using their own heavy bias and getting caught up in trying to not harm people, I'm afraid you just hate my writing style. Maybe you don't like the inline quotes? idk. Also I can't imagine wasting the effort to have a bot debate people online if I don't care enough to do it myself.
The whole reason we have those types of employment and public accommodation laws is a special case though. In terms of employment, we prefer this to a world where black people or women can't get jobs, because jobs are necessary, or can't enter half the establishments because people witnessed that Jim Crow was a shitty and shameful situation. And I do stipulate that that doesn't mean the same as "all women have the right to a job at my company upon demand."
But why don't we also have laws criminalizing things like refusing to be friends with $SKIN_COLOR people? I think it's because it's only in those specific realms like employment and public accommodation where we have created rights. The right to shop in a place that is open to the general public is a right Black people got from a law. And the right of people to be considered for a job without regard to their membership in certain protected classes is something the Equal Employment Opportunity Act of 1972 created. There is no right of foreigners without a green card to enter in the first place - CBP can completely legally say no to anyone, so no 'counteroffer' of conditional admittance could be inappropriate. The only exception I can think of is misconduct of the officer, e.g. 'I'll admit you if you give me $10,000' or a more unsavory favor. But with that already being illegal, I don't think it is too relevant here.
