This isn’t really a derailment of the thread, in that you have defined a boundary that I would not accept a democrat crossing.
If you held your view for optimistic reasons, that we don’t need anti-discrimination laws because there isn’t discrimination anymore, then I would disagree with that optimism, but I wouldn’t really be able to be upset about it. It is hard for me to get angry at people fro being optimistic.
But, I would disagree with you in that the idea that “no one may be compelled to belong to an association” doesn’t mean anything when you have voluntarily put your services into the public sphere. No one can compel someone to bake a cake for them, for any reason at all, unless that person has chosen to open to the public and bake cakes for the public. At that point, the public does have an interest in making sure that those who are using the public resources for their personal gain do so without discriminating against members of the public.
As discrimination is currently fairly widespread in spite of laws against it (it is actually really hard to prove that you didn’t hire, or fired, an employee for illegal reasons, and even harder to determine that is the case for clients), and we are not that far removed from times when it was not only open, but encouraged and sometimes even the law, I don’t think that we are anywhere near the level where getting rid of the laws will not cuase a fairly immediate and drastic increase of minority abuse.
So, much as you may think this is a derailment, you are right on track here. Your opinion that anti-discrimination laws are unnecessary or even in violation of the UDoHR is one that is irreconcilable. I would consider someone with that view to be well outside of the tent that is the democratic party.
I can accept democrats who are personally anti-abortion, and I can even accept democrats who would allow or even push for legislation limiting elective abortions past 20 weeks, so long as exceptions are allowed for health of the mother and cases where the child is a product of rape or incest, and they don’t really touch anything under 12 weeks. (or limit access to contraception and the education to use it properly)
I can accept democrats who are pro-gun. Pretty much anything short of demanding that everyone carry a gun at all times, I don’t really care. I may disagree with them on the policies that they would go for, but I wouldn’t consider pretty much any reasonable view on guns as being a non-starter.
But, as far as minority protections go, that one’s actually pretty important, and a bit of a defining characteristic. I could certainly accept a democrat who looks into tweeking anti-discrimination laws or affirmative action initiatives to achieve more favorable results, but I could not accept a democrat who was willing to remove those protections entirely.
