Cultural norms can be good or bad. There are plenty of bad norms in the US. I won't speak to Asia's norms, and wasn't talking about Asia. I was talking about my own culture in the US. Perhaps people in Asia have other wholesome ways of expressing these things. Or perhaps Asia's cultures are damaged and damaging like my home's culture is. I don't know.
But your comparison feels like whataboutism and deflection. Humans wanting to touch and to be touched in non-sexual ways isn't weird or shameful. That's what I'm addressing here.
Humans not wanting to be touched is OK, too. I'm not advocating for nonconsensual hugging or touching.
What's weird to me is how even discussing it brings out instant defensiveness in some folks, which is kind of proving the point that I am trying to make.
