Can you expound on that? Intuitively the bolded part seems to change the equation a bit. A hyperbolic statement mutually-understood to not be serious doesn't strike me as beyond the pale, even if that's not how I would communicate with my wife.
I do sometimes threaten my children with being "stomped into a fuzzy paste" - a dire threat that is typically greeted with laughter. Is that also not OK?
There's a lot of room between "not OK" and "beyond the pale", but yes, I will expound a little.
The main joke of the Honeymooners was Ralph would come up with some plan, it wouldn't work (with hijinks), he'd lose his temper and yell, bluster, and blame other folks, including threatening to hit his wife, then he would be shown the plan's failure was his fault and be contrite until the start of the next episode. Rinse and repeat. It's a show, and fiction, so we can take the humor for what it is and have some fun.
Actually treating people like that would not be OK. It would make you an ahole. Ralph (the character) was also threatening Alice when angry. He wasn't joking (as I assume you are with your children) he was genuinely angry when he threatened violence. That's actually the foil of the show, that he gets angry when everyone else can see it's his fault. It is often pointed out (even in the wiki page) that Alice knew he wouldn't really hit her, and he never did, but he was still an ahole to her for the entirety of the show. It's not OK to be an ahole to your wife even if she takes it.
A note here: I'm not saying the Honeymooners wasn't funny, or that it should be boycotted or purged or anything, just that Ralph (the character) was a jerk. While funny as a caricature, one shouldn't emulate that behavior.
Which brings us to:
Of course it is, but if the US has pretended it's not when they do it, that should be the legal precedent now. Goose, gander, sauce, etc. There's plenty more here to put the guy away for a long time.
No, you're backwards. This guy should go down for torture, AND the US should admit it was torturing people. The fact that the US government did something wrong and claimed it wasn't doesn't make the act not wrong, it makes the US government wrong.
