If they are then they need to be acting like it and to be speaking up about the jerks and saying, "that stuff is unacceptable". When people are being jerks in a public forum, the only way to fight that - and to ensure that the forum is not taken to be supportive of the jerks - is to say, "that is wrong, that is unacceptable, it offends me, and you should find somewhere else to go if you want to say crap like that; we don't accept that here."
Don't feed the trolls only works when it's clear otherwise - through positive affirmation by a majority - that the trolls are indeed trolls. It's not clear at Perlmonks. For instance the poll is still up and unchanged.
