Where did woke ideas start to spread?

    The phenomenon, it seems, did not begin in America (see chart). Countries such as Australia, Canada and Sweden in fact led the charge. 

"woke" started in the African American community. Its roots are in black activism. It was later co-opted by white leftists and - as with everything else white leftists take from the black community - all but entirely removed from its intended political context, that being opposition to white supremacy.

To ignore this in service of an alternate history where "wokeness" began in Europe and Australia and didn't even take root in the US until after the millennium, and only when the "social justice warrior" movement in the US began to become culturally relevant, is grossly ignorant to the point of seeming like whitewashing.

What "woke" means now is irrelevant - at this point its been so corrupted that its only stable point of equilibrium is as an anti-leftist pejorative. Even the article couldn't resist an eye-roll or two, because no one uses "woke" in good faith anymore.

But we know where "woke" ideas came from, and it wasn't Foucalt and Derrida.

Of these I'm only familiar with Canada, in which the economy revolves entirely around government spending, with a few quasi-government oligopolies thrown in (banks and utilities that also have effective taxation power). This kind of administration heavy system is exactly where these ideas proliferate. They are all about exerting power over others, and in a bureaucracy that's disconnected from the real world they are a great way to jockey for power, so it's not surprising to see canada as a leader. No idea if this holds for the other two.
