It’s simpler than that.
Libs just think they are smarter than everyone else and therefore not only does that mean they want to rule everyone else, nobody can be as good as them without their help.
“Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron’s cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience.”-C.S. Lewis
