> is it stereotyping to say Black people tend to have darker skin

Your analogy is altogether misplaced.

> But? Isn’t that ok?

No, it never is. The hallmark of civilization avoiding collateral damage and protecting the innocent, without which we're animals.

> And if the domain is super cheap to register, is overrun by bad actors,

That is not established. The bad actors merely make noise, and get reported. The good actors stay out of the news.

Your argument is bogus because filters absolutely can be nuanced, operating at the name level. It is a non sequitur for a filter to operate at the TLD level.

> My point is that at a macro level stereotyping is absolutely wrong. But at a tactical, day-to-day lived experience level

Huh. That is just laughable and sad. Stereotyping is wrong at every level, and it's even more wrong at the everyday level.
