I recommend everyone watch it. Keep a finger on the 30 second skip button to bypass the really degenerate stuff though.

The reason you should watch it is because it is an instructive illustration of what they see when you disagree with them. And of how much they hate YOU. Not some abstract concept, but you personally. Sam Hyde wasn't even slightly exaggerating when he said “When we win, do not forget that these people want you broke, dead, your kids raped and brainwashed, and they think it's funny.” If anything, he wasn't expressing the sentiment strongly enough.

Remember those lessons for when the other side asks of you any mercy or human consideration, and for when the people supposedly on our side call for restraint.
