Sargon of Akkad is the psuedonym of a British YouTube user whose channel has a lot of social commentary. He first came to my attention via Gamergate, which he supports (as do I), and is the mind behind "This Week in Stupid".
Here he has two videos on Saul Alinsky and his infamous political operations manual, Rules For Radicals, which Social Justice cultists and fellow travelers have followed to successfully seize power in much of the West to the detriment of Civilization and the benefit of Empire. You're wise to (a) watch them and (b) get yourself a copy of the book to see for yourself. (Buy used if you can.) Once you know the move, you can figure out the counter quickly and easily; these are the moves, so learn the counters.
