"Also, in the past, Asian Americans, period, were victims of serious discrimination coming from the government, a practice which has since been abolished but whose residues still haunt Asian men even today as they are not seen as fully American by the US society"
If you're referring to WWII internment and immigration quotas, they have nowhere near the effect Jim Crow had in the early 20th century, or that illegal immigration and the stigma against it have now.
I actually find that most asian girls are with asian guys. They're with the asian guys with game, who are confident, drive a nice car, have a good job, and has options.
If you don't have those things, no matter what race you are, you're going to have trouble with the ladies.
