Except that is explicitly not the argument of those that actually want these folks deplatformed, but those that fear their own speech will somehow be in danger and want to solve every issue in existence with technology. The "it could happen to you argument" is really tiring. Gab is abusing your idealism. If you spent any amount of time on Gab you'd know it was a deeply right wing bubble full of hate, with a lot of harassment coordination happening. I say has because it has gone a bit out of fashion and these people moved on to Parlor now. This is not merely a place where people have opinions (that someone thinks are bad). That exists on YouTube. If the bar really was "the consensus thinks you're wrong, filled with bias and not interested in productive exchange", Stephen Crowder, Dennis Prager and Tim Pool would not be on YouTube. James Damore would not have been on every conservative program in existence. Society has drawn a line, and you can argue if it's too strict or leniant, but to say we could never draw one without the possibility of false positives is defeatist idealism. Sites like Gab or, let me dare mention their name, Kiwi Farms, are different. They facilitate material harm in a very tangible clear-cut way. They are very definitely beyond the point where tolerance does not actively work to destroy itself.
