That reminds me, actually, of a caveat I should have mentioned in my reply to Doug. Most of my own experience of consensus decision making has been in Europe, and I think the US may well have a stronger tradition of individualist anti-majoritarianism (I'm currently a TA for an Intro American Politics class, and it's a struggle getting students to articulate _why_ it's a good thing that Wyoming has as many Senate seats as California - the assumption that "minority protection" in the form of equal representation for smaller states is a good thing, is very strong). So, even though I don't think Bookchin's theoretical arguments against consensus are very strong, there may be reasons why consensus is more likely to be interpreted in problematic ways in particular contexts.
