There are also Rights Based Ethics, which basically look to balance personal rights and societal obligations. It reminds me specifically of certain American ideals, and I think that's pretty interesting.

That's pretty interesting, I thought it was meant to be ironic. Like "there's no way they can be for real right now" type of thing.

I think the reason so many people put effort into responding to this is similar to modern ragebait, except this wasn't outrage on purpose, just outrage. Whenever people see something that they consider wrong or something they generally disagree with, they're often inclined to speak up about it.
