I went through this one a couple of times at 1.5X. speed.
Remember when you were a kid? Remember all those ads for Charles Atlas body-building courses and the like?
Social Justice is basically selling programs where you can be weaker and more pitiful. It's like taking a course where, instead of learning new things and improving yourself, you learn how to be stupid and whimpy. Instead of becoming fit and strong, you become skinny and weak and lose the girl (the girl you couldn't get anyway) at the beach.
Instead of "Be All You Can Be" it's "Be A Loser" or "Don't Worry, Be Weak and Pathetic...and get paid for it!"
As we all know, it's insane, but it isn't sold. It's spread by brainwashing and indoctrination.
