Being that kind of person isn’t bad or a negative though, and framing being confident in having knowledge as a negative is what drives tyranny, discourages education and critical thinking, enables propaganda to be so effective, and destroys society.
That guy smugly bragging about reading a Wiki article could have legitimately never crossed it before and was genuinely excited in it for the sake of it, and here you are destroying legitimate intellectual curiosity just because society told you that was a no-no. Who’s really more shameful?
