There's a difference between the First Amendment and the principle of free speech. I'm annoyed most everywhere when speech minders, school marms and scolds intervene.
I think you know I'm not a Trump guy. Efforts like this truly do play into his hands and foment hatred of the effete, elitist ninnies who behave like this. I think you overestimate how many people actually despise Trump and you probably underestimate how many people love to see it stuck to the people I mentioned above, who look down on them.
