Conservatives have the same (or a corresponding) tendency, no doubt, but sometimes progressives charge forward in their righteousness in a way that justifies the opposing arguments against which they’re railing. Former Democrat legislator and gun-control advocate Linda Finn recently offered a fine example on Twitter:
The @nra should be tried for treason. They have been fostering conspiracy theories against the govt for years to get men to buy more guns and ammo. They are among domestic terrorists.

Why, yes, how unreasonable for people to believe conspiracies! A politician and activist who wants to use government to criminalize a member-supported group that she doesn’t like should perhaps shy away from promoting her opponents’ fear of government as evidence of their insanity.
