No sources, pure bullshit. This is a common right-wing conspiracy theory: just throwing words like "Frankfurt school" or "post-modernism" without understanding them, accusing "the Left" (with a capital L, as if it was a secret cabal) of orchestrating a decades-spanning Grand Plan to indoctrinate children, etc. Insanity.

Also makes me laugh whenever I see right wingers accuse the left of post-modernism, when Trump is the most post-modernist guy I know. The man literally never says the truth: according to him, we destroyed 100% of Iran's armament [1], Iran were the ones to strike their own girls school and oil prices are as low as ever.
