I started seeing it just before 2019 although it seems like it was a big deal in universities since 2010 or thereabouts. It just wasn’t on my radar until say 2018. There seems to be a bunch of collectivist / Marxist ideologies that are all getting commingled. There’s intersectionality (oppressor / victim), ESG / climate, and even covid vaccines somehow got mixed in. I personally group all of the Marxist stuff under “woke” but I realize some may only use the term for the social justice warriors. The common thread is that all of these ideologies are anti-family, anti-human, anti-prosperity and anti-freedom. Thankfully I’m sensing the pendulum swinging back a bit on that craziness.
