Bird site, free speech
I have to call bullshit on this. The comic is correct.
The problem is, when you go to a white supremacist house party, they're going to consider the anti-racists to be assholes and show them the door. That doesn't mean the anti-racists *are* assholes.
The argument in the comic isn't "shallow." It's principled. It applies no matter who is doing the "censoring".
The key is that "censoring" only matters if you respect the opinion of the censor. If you don't, you can just ignore them and their property/platform.
And if there's anyone who still legitimately respects the leadership of Twitter, I've got a bridge to sell you.
