Drive through the neighborhoods of Chicago, through enclaves of Irish, Polish, German, and Jewish people. You won't miss them: the signage will abruptly change to Polish, or the streets will be full of men in suits wearing their hair in payots. This is a form of diversity, to be sure. But it's not the kind we're concerned about.

The problem here is the word "diversity", which is very easily hijacked to distort discussions. I think we're all pretty much on the same page that the concern being addressed here is the exclusion of specific, prominent ethnicities from SFBA tech culture, not the absolute number of different ethnicities being represented.
