Beating your wife? I could not see as a cultural thing.
That's kind of exactly my point, though. I see claiming being loud and inconsiderate to others as people practicing their culture to be just as disingenuous an argument as saying wife-beating is a part of Irish culture that just has to be accepted. It's just brought out to defend bad behavior, often with the implication that if you continue to criticize said behavior, you're automatically in the wrong, having revealed yourself as bigoted against whatever group you're criticizing.
Honestly, I often think Americans need to learn to live apart from each other these days. I'm very skeptical of the notion that the US can ever function as a coherent political unit again, and it might be better for all to just cut bait and move to an EU-esque free movement regime. Let New England, the South, the Midwest, the West Coast and whatever Alaska and Hawaii want to be each be their own independent countries, but any citizen of one has the right to move to any if the others and work immediately. If Republicans want to enact their own little Handmaid's Tales in the deep South, they can go for it, but no moaning when women and POC decide to move elsewhere. The non-GOP hellscape regions can implement social safety net programs to allow anyone who wants to leave the conservative regions to do so, regardless of financial means, knowing they will have housing, food and healthcare when they get to a civilized country.
It really feels like some backwards regions are holding the whole country hostage at this point.
