OP, a lot of your points are being made with the assumption that Europeans were (or are) upstanding, virtuous, hygienic people when history actually shows them to be the opposite.
Despite what the white supremacist says, Europeans weren’t able to conquer the “New World” because of “superior weaponry”.
No, most of them were nasty as fukk and used their diseases to disarm and subjugate indigenous populations before outright attacking them.
I say that to say, why would you think that people shytting, pissing and menstruating themselves would be enough to bother the typical depraved CAC of that time?
In 2024, people are desperate enough to shove drugs up their ass and hop onto an airplane or cross the border in hopes of making a few hundred thousand.
But you really believe that CAC slave traders, who made billions, would let the shyt you’re talking about stop them?
