I've been thinking the same thing, Blake. Most of my contact with FI supporters is with the "FI majority" (I am a sympathiser in Solidarity, after all), and the characterisation they tend to give to the minority view is that they're opposed to broad anti-capitalist formations, and simply want to build FI sections. Fortunately, it seems like that's not the case; what the minority tendency is arguing is that FI sections should not have to dissolve themselves into these broad anti-capitalist parties.
While I can kind of see the logic of dissolving the LCR into the NPA, it remains that this isn't something they had to do, as the examples of the Portuguese Left Bloc and Enhedslisten in Denmark seem to show.
