I see your point.
My wife who is a Japanese-American and born in NYC has made comments echoing what you said.
For example she was far more anti-Hillary then for Trump in 2016. To her (and she** would say to other Asians!) Trump is too immodest & ill-mannered. I think she may have a point at least in regard to Trump. The other problem is the GOP has allowed itself to be defined by the Rats to Asian Americans as racist, intolerant religiously & too Euro-centric to accept “others”. There is the other issue, the conservative message (again as defined by RATS) is viewed as overly emphasizing the individual meaning defined as selfish! There is a lot of contradiction in this (Humans being inconsistent whodathunk!) No one is more individually competitive then Asians! - maybe more so then Jews! And actually many of the same false notions that Jews have about conservatives apply to the Asian view!
Now why the **, my wife was born in NYC and lived there until she was 14. She has Trump’s accent & his bombast! Of course every time I point that out I have to run and hide! :)
LOL - I think it is Trump’s mannerisms that she objects to. Policy wise, Trump is likely doing what she supports, particularly in the social area, including holding criminals accountable, etc.
