Of course "deplatforming works." Fascism works. Totalitarianism works. Terrorism works. That's why people keep embracing such ideologies, even though our culture nominally considers them to be among the greatest of human evils.
The hed of this op-ed is misleading. No, you shouldn’t stand as soon as the plane lands; wait until you’ve arrived at the gate. But yes, if you’re on the aisle, you should be preparing yourself and helping others prepare to deplane, not sit in your seat until it’s time for you to actually move. I don’t understand the people who think that we should be slowed down by telling people to remain seated.
