The 'bird' cartoon strip reminds me of the anti-gun people. They aren't upset about not having guns of their own. They're bothered that we have guns. So, rather than get their own, they work to have ours taken away.
It seems to be true of many groups. "I can't be happy about being (poor/black/female/whatever) until you feel guilty for being (rich/white/male/not-whatever)."
