OK, maybe arbitrary isn't exactly the right word. I meant that there's no indisputable link between ethics/morality and law.

You say that they "were passed in response to actual and widespread discriminatory behavior". That's true. But they wouldn't have been passed, notwithstanding discrimination, without enough political support (of one sort or another).

I mean, there's also been discrimination in health insurance rates based on preexisting conditions. And gender-based discrimination in vehicle insurance rates. The Affordable Care Act more-or-less restricted the first. But the second is still the norm in the US.

I would say the second one should be illegal.

There is plenty of ways to lawfully discriminate in this country. You can even still have discriminatory policies in employment if you can show it directly relates to the job.
