The science fiction author / scientist David Brin has a much-read (+100 comments sometimes) blog . I'm a sucker for Purple State ideologies that depolarize the polemics of both sides for dialog and Brinner is a liberal that's sympathetic to conservatives, noting that people on the left should be receptive when conservatives have:
"reasonable 'Goldwater-style' objections, instead of the shrill mania pouring from the Murdoch-Limbaugh-Fox nexus. We should be ready, whenever this happens, to heap on positive reinforcement rewards! The biggest reward of all? To actually listen."
One long post from Brin in which he brings together a lot of threads is here.
