-I highly doubt your Half-Asian, if you cannot tell by looking in the mirror if your White or what not, there is something wrong there...90% of the time, Eurasians look Asian with a funny look any White person can pick out, although there are time's when Eurasians look very White, its extremely rare, the only Eurasian I can really think of is that guy from Saved by the Bell…..Most the time the “White” looking ones are North East Asian – European Mix.    -If you look White, act White, you are White...unless of course you open your mouth and say your not…… :rofl ... Seriously until you said something who would have any idea?     -But if you all worried about your Racial purity you can go get a DNA test….
