Actually, you can’t discriminate against whites.
If someone discriminates against you with the stipulation: it’s because you’re white, you can bring down the wrath of the justice system on their establishment.
If a shop has a: “no whites” sign, guess what? That’s 100% illegal.
Ugly… yeah, I’d give you that. Some ugly people discriminate against ugly people, and it’s a shitty thing to do. But I have no idea how you’d get a discrimination lawsuit against them, since ugly is subjective.
And isn’t polygamy, at least in terms of marriage, illegal?
