One way or another, it means that to adopt even one Left-aproved position will result in having to keep company with a huge number of unsavory types whose agendas bear no relation to one's own. That goes a long way toward explaining why the Left is almost entirely composed of the vulgar, the unwashed, and the generally unacceptable. They can bear one another; others are more particular.

To further add insult to injury the Left then demands its fecal "package" be wrapped up in an American Flag.
Back when I protested against the bombing of Serbia I would get asked if I was going to the next protest (e.g. a Free Mumia protest). I kept wondering then how the increased numbers of protestors weighed against the dilution of the anti-war message. It depends on the situation, in that case it made some sense to have a left-right coalition against the center-left warmongering president.
