The only whites who really had accents were the Italians and Irish. If you go to the few italian areas left there is still an accent in their speech pattern.Russians and Eastern Europeans however do not have that old school accent they sound like regular whiteboys.
The only Hispanics that have a NY accent are Dominicans (heavy), Ricans (heavy) and some Colombians. Mexicans and Central Americans don’t display an NY accent like that. I also never really seen a Mexican here even act like an La Mexican either.
My grandpa was Irish (born in the 40s in Brooklyn) and he had somewhat of accent I guess, but it wasn't really that strong unless he was joking around. I think most Native whites in Brooklyn are either Eastern Europeans (regular whiteboy like you said), Hassidic Jews (I don't even know what they sound like), or middle class to rich people from Northwest Brooklyn neighboroods like Park Slope (also regular whiteboy).
I didn't say they act like an LA Mexican but they sound like them usually (to me at least). I work with a Colombian chick from Queens and her accent in no way resembles a classic NY accent, she sound like an immigrant lol.
