We are still searching for an appropriate name for the opposition. We've been painted into a Godwin's law corner about "denier", but we can't tolerate "skeptic", because that is certainly not what they are. They have no skeptical habits of mind, choosing to believe congenial evidence and dismiss evidence they dislike.
It strikes me that they are doing slight of hand by calling themselves "skeptics". The definition of the opposition group is not their beliefs, which indeed are all over the map. The definition is their behavior, which is all about avoiding any policy whatsoever. It's easy to come up with an adjective for this, "reckless". Oddly, I can't come up with a good sticky noun for a absurdly reckless risk-taker. Maybe there's something in another language? Maybe there's a character in literature? I think the point is that their "inaction" is intended to perpetuate extreme and dangerous action. Let's face it, nobody knows for a fact how things will all turn out. But the longer we delay, the more severe the problems of our future selves and our descendants! "Skeptic" is hardly the name for this! "Denier" or "denialist" really isn't bad, but in addition to rubbing some people wrong, it doesn't capture the mindboggling recklessness of their activities.
As for ourselves, those who feel the discussion is usually a bit too leisurely and cool, I prefer "Cassandrites".
