"I completely disagree. Why does sloganeering about "social justice" and "freedom" take precedence over daily life?"
Um... I said "participation in struggle," not 'sloganeering.' For a good example of the difference between "participation in struggle" and 'sloganeering' compare the George Jackson Brigade to the Revolutionary Anti-Imperialist Movement, Denver.
I should clarify what I meant by daily life: Some parts of daily life are basically insignificant:
What you buy, where you shop, where you hangout, what close you wear, how you style your hair, what you eat, whether or not you can claim the 'moral high ground'... etc. These things matter relatively little.
There is a part of daily life that is very important: how you relate to the people around you.
This include: your expressions of solidarity, who holds the burden of work (and what types of work), the way work (and different types of work) are valued, the presence of consent, how you deal with confrontation, how abusive relations are addressed, who takes up space, who is allowed to use space, who is pushed out of space, and many more things.
I agree that self-important groups that think the revolution depends on them are not the way to go. The George Jackson Brigade was a good example of a group that said its work was to support and enhance a broader movement, like when they destroyed construction equipment at a site that people had been protesting the development of. Not only did they stop the construction project, but they got all the charges dropped against the protesters.
