"The worst thing is for the know-it-all-lefties to piss people off with condescension, which happens a lot when something new gets going."
Not sure you're addressing me, Garry, but if you are I'd just like to say I don't claim to know it all. I learn as I go. Sadly, questions can be condescending... or perceived to be condescending ... which leads to defensive stand-offs. But also, questions can improve movements - especially new ones where not all issues have yet been ironed out? Surely any movement should be open to questions, rather than lock down in a closed-circuit position that brooks no query?
