Was Scalf Referring to Blacks in These Posts?

[Boris]

First of you don't know she's not black.

Secondly, even if she is white, I'll bet dollars to donuts that over 95% of the Lakeisha's in this country are at least part black.

Third, in Scalf's post he was very obviously expressing disdain for a particular subculture. We are left to guess which subculture. Fortunately Scalf leaves us lots of clues and when you put them all together it becomes clear that he is ranting against the black population.
