No true Scotsman and Godwin’s law, nice. Anyways, BLM is an obvious continuation of the civil rights movement, and calling them “slacktivists” is derisive and reductionist.
Protesting until you die of old age is not what it used to be. The surveillance of the modern world makes protestors into easy targets if they ever become a true threat. The powers that be have learned plenty from the civil rights era.
Nobody should have faith in any nation to erode in the first place. Every single one has fucked over their neighbors and their own populations to further the ambitions of the rich and powerful. Look to the erosion of antitrust and privacy laws to see where we are headed. Look at how SOPA and other protests have gone. You seriously think nobody knows how to protest anymore, and it’s just a generational failing? Despite the obvious ways the oppressors have adapted to the modern world?
