If having these preferences gets me called racist, then fine. Whatever. All I wanted to do was remind people that these cultural differences exist, and that I really do not want an Eternal September that threatens them. Hell, I even think that America probably should have somewhat looser immigration laws than they currently do.
So go ahead, by all means, have whatever views you want. Espouse whatever views you want.
I don't really care, because I don't know you and will never, ever need to work with you, do business with you, invite you to my wedding or holiday dinner, whatever.
All that said, dog whistle politics is a real thing, even if you or other people here don't know about it. And not knowing about the specific cues just means you're not part of the group that'll respond to that dog whistle.
If you're not already part of the subculture primed to pick up on these cues--if you don't hear the dog whistle--you don't get what the speaker/writer is saying.
The famous Lee Atwater quote is a good example of this (https://en.wikiquote.org/wiki/Lee_Atwater).
It's plausible deniability for espousing racist views in public.
