I remember something in David Friedman's writing to the effect of how no layman ever argued with him about anything in physics (where he has his degree) but everyone feels qualified to argue with him on economics (what he is professor of). I think linguistics is similar. I only took a couple courses, but I frequently see people offering up opinions as if their instincts were a valid counter argument to well established science (like whether people have a conscious grasp of the grammar of their native language).
