It’s mostly Asian men that are negatively stereotyped. Usually as being “weak” or “nerdy” or “feminine”.

Non-Asian man + Asian woman couples have long been normalized. Asian man + non-Asian woman couples were/are comparatively extremely rare.

That said, thanks to things like the tech industry (nerds are no longer automatically “ewww”) and the popularization of K-Pop boy bands, I’d say the image of Asian men in the West is on the rise nowadays.

Coming from the states to Eastern Europe I was shocked at how many asian-man/white-woman pairings I saw in Budapest and Krakow. The asians are mostly Chinese playboy sons of mainland or impex business owners and often obnoxious as rich brats tend to be. Completely different vibe from my SoCal suburban violin-playing hapa friends who studied at UCs.

When you say the West I think the stereotype only really applies to the USA and maybe Canada.

my flagged comment (which i said would happen) was about the phenomenon of AMWF couples in eastern europe highlighting the structural conscious and subconscious racism towards Asians but especially Asian men in America confirms my point exactly.

edit: there seems to be someone who was upset by my original comment and is now just routinely going through all my comments and flagging them.

There is also a lot less misandry in general. The old "men are dumb and messy and gross" trope doesn't hold much relevance. Women are more likely to view a man as just another person and not a member of The Evil Patriarchy.
