You can't make this stuff up!
Jamey Keaton reports for AP - G-8 Protesters Clash Among Themselves:

ANNEMASSE, France - The thousands of protesters converging on this year's Group of Eight summit are an eclectic bunch with a grab-bag of divergent interests — so much so that some of them clashed on Saturday with Socialists sympathetic to their cause.

A group of about 350 protesters disrupted a meeting of France's Socialist Party, tossing rocks through the windows of a conference center and accusing the party of not being radical enough.
...
The Socialists were meeting Saturday as part of a "counter-summit" to address issues critics say the G-8 is ignoring, such as the woes of immigrants and refugees in Europe, debt relief and African development.

Kewl! But there's more:

The activists divided themselves up into the two camps to show their diversity. One is the "intergalactic village" — grouping environmental, anti-nuclear or other social activists. The other is the "anti-capitalist, alternative, anti-war village."

Hmmm, who has the tin foil beanie concession?
