sporty,
We obviously didn't parse the AM's statement the same way. Since the title of the poll is My cow-orkers mostly..., I read it as:

Of my cow-orkers, the Java guys despise..
The opinion that this was not a generalization but a distinct select group became stronger when I read the last sentence: I'd like to rewrite my managers in Perl

The word 'my' ne 'all'. In any case, I agree that in general, people make a lot of generalizations on things offend the group as a whole or at least individuals that do not fit the generalization. I just didn't see that happening here.
