You monster. I'm unfriending you this instant and telling all of my friends they have to unfriend you too in the next 6 hours or else I'm unfriending them also.

While I'm kidding about the op, I see this all the time on my feed. Just today, I saw someone in my Facebook feed just today demand that everyone unfriend person X right away because they're a Trump supporter, and he would go through the list of mutual friends and unfriend everyone who didn't. I'm far from a Trump supporter, but I find this behavior childish.
