In bygone times, when you came across a political commentator you found annoying, the solution was to change the channel. Now, an online mob forms with the fervent intention of silencing the offending voice. To the cyber barricades! Hashtag campaigns, public shaming, boycott the advertisers! And ironically the mobs are often composed of those who label their opponents “authoritarian.” Ah, but the Constitution’s 45 word First Amendment and its resilient spirit of free speech has proven to be the most reliable bulwark against real authoritarians.
