A few years ago, I might have agreed with that. Now, would have to say that’s nothing more than cognitive bias, and the east, west, makes no difference in and of itself.
I first went to Thailand when 23... never really dug Asian women before, though when came back, oddly found I wasn’t into western women anymore and really dug Asian... fast forward another 7 months in Thailand, 5 years in Bali, and back to Canada with an Indonesian wife... can safely say: east/west is far too broad a generalization. There are good & bad, graceful and non-graceful, crazy bitches and true queens, etc, etc on both sides.
Quality is more dependent on the individual than culture.
Attempting to argue against that, you’re more less just resorting to racism.
