Modern critical thinking definitely owes a lot to critical theory. The ability to look at statements from the government and think about the ways in which the statement might mislead or outright lie is directly tied to the original climate of the Frankfurt School.

Typically, we refute philosophical positions by some sort of evidence. Without evidence, there's only opinions, and those are cheap and limitless. Indeed, in this very thread, basically all of the links and evidence have come from only one side. The only claims you've made with any substance are about phrenology and "millenials" in "institutions". I tackled the former; the latter is easily handled by remembering that critical theory started as an academic endeavor, and never really has been foreign to higher education. Although, as I describe this latter position, I'm reminded of the belief in the Cultural Marxism conspiracy theory. I don't know why people believe this; Marxists are pretty open about studying labor and power, and the fact that critical theory is a decades-long multidisciplinary research movement rather than a single meeting would suggest that it is not hiding some cryptic agenda.

It sounds like you think that critical theory ought not exist at all, but we would have to remove an entire score of history and philosophy from our discourse in order to do so; you'd have to prevent the First World War somehow.
