I would definately join such a group. The idea is basicaly an unparty-like party. Which appeals to me very much. What a large party like this must do, is collect with it the smaller parties around which agree with its principles... to make a more massive and complete census of modern communist and anarchist idealogy.
The most appealing thing is not running into ML or MLM supporters.
He who was previously the money-owner now strides out in front as a capitalist; the possessor of labour-power follows as his worker. The one smirks self-importantly and is intent on business; the other is timid and holds back, like someone who has brought his own hide to market and now has nothing else to expect but - a good tanning. - Karl Marx, Capital Volume I
