I cut back a bit on my dKos reading for a couple days (heck...I didn't even go away) and now the whole site is boycott, boycott, boycott.
So I sit down to read the boycott diaries. What I get is an awful lot of heat and not much light. Lots of statements of solidarity, with virtually no sense of the whys of this movement.
Finally I stumble upon a couple diaries that make some accusations of "disparate impact" without really solid evidence.
