“I don’t know” can be fixed. “I don’t want to learn” is a big problem. “You think you’re better than me?” is worse than “strange women, lying around in ponds, distributing swords” as a basis for government.
Depends on the “form” (or context) of Elitism. On the one hand obviously experts should be consulted on most subjects, especially on the hard-sciences, and it’s too bad we don’t take them more seriously, which is no doubt at least partly due to the rise of right-wing populism. And people with experience governing should usually be expected to be better at it than those who don’t.
That said while the “Crazed Ivory-Tower Intellectual who thinks Citizens should submit themselves to their own highly insulated elitist sub-culture” cliche is perhaps anti-intellectual it is oftentimes very real when it comes more to the Humanities and “Soft-Sciences” and they should be approached with extreme caution. At least until the overt extremists (particularly the radical postmodernists) lose more ground there.
