This is not the first time I have seen Greenwald bash Kossacks. It seems he trolls the site looking for anything that may look Obama supporters bad. Here is the latest instance:
I probably agree that the diarist didn't take the best course of action in this particular instance. However, GG seems obsessed with making Kossacks look bad. It is very bizarre.
Update: as one of the commenters pointed out, "I recommended this diary myself, because of the diarist's second thoughts." But of course Greenwald always assumes the worst of Obama supporters. It is easier to hate them that way.
