For several years, we’ve seen conservatives lambaste the modern American college campus as a hotbed of intolerance, because of policies and the occasional protest (or worse) that sometimes shuts down right-wing voices like their own. This is the one (and practically only) place where I occasionally find myself in something close to agreement; I’ve criticized events in Berkeley and Missouri as antithetical to my long-held view that bad speech should be drowned out with good speech, not silenced. But the 1st Amendment exists primarily to keep the government from acting as a kind of thought police to monitor and control what people say — exactly the strings Team Trump is trying to pull in North Carolina.
