It kinda hurts my belief in humans when I see radicals choosing to expend significant amounts of energy on tearing down the works of other radicals, on the basis of overall minor issues or outright smear.
People who only know how to dismantle but not how to build are a real obstacle for real change to occur.
This doesn't mean you can't criticise your fellow radicals, but don't go on a f-ing crusade against them, and don't make dismantling your sole activity.
