1)Purism: criticism of black bloccers (will use this as term whether or not disruptive elements call themselves black bloc or not) is not criticism of Occupy Oakland as a whole.

In that case it isn't criticism at all but merely individualist kvetching. For those of us not _part of_ Oakland Occupation it comes to us as a whole, and weeping about arbitrarily selected fragments of it should be left to the official cops.
This whole thing gets worse and worse the more the alleged "critics" try to justify themselves.
