Is community possible?

My previous post was a frustration with a disconnect within activism which, oddly enough, is what Sullivan addresses in chapter 8. She uses theories of Secomb and Nancy to show that differences within a community that are irreconcilable keep movements from moving in one direction. Instead 'community' is an umbrella term, like the queer community, that serves to show generally where the conflicting groups stand in their struggle. The 'identity' of the community is not essential or fixed but changes as the groups struggle to become the majority that will speak for the community and police it's boundaries. She ends, however, by using a quote from Derrida saying that community is not possible with this lack of unification. I have to disagree, simply because in looking at the diverse perspectives coming from our class, we still form a close community that agrees that there are major problems that need to be addressed, and I feel like even though we have different opinions about issues concerning assimilating and pornography, etc, we could still work together in a community on other concerns for lgbt people.
I personally would still say we were working with and for the same community.
