If you go by most of what you see in the media, you would think politics is governed by some strange version of Newtonian physics. “Both sides” are perennially to blame, and if there’s ever dangerous excesses on one end of the political spectrum, then they must of course be evened out by the existence of equally dangerous excesses on the other end.

It’s why, after George Soros was mailed a bomb, Chuck Schumer felt the need to announce that “despicable acts of violence and harassment are being carried out by radicals across the political spectrum.” And why the New York Times, after more explosives were sent to individuals hated by the Trump-loving Right, decided the explosives were adding “to [a] climate of overheated partisan rancor.”

Yet we’re now at a moment when it’s indisputable that only one of these “sides” has actually become a vehicle for dangerous, violent extremism.
