Content moderation is a form of free speech. You don't get to tell others what to do just because of your wayward political views. They taught us this in elementary school.
I agree - but as I've said above at some point, at some certain size, moderation goes very quickly to censorship when you go deleting the largest platform by far for one side to discuss things, when they're NOT actually doing anything that thousands of other subreddits do that aren't banned.
No matter how you try to shoehorn it in there, it is not censorship for someone not to provide you a platform. Your viewpoint and perspective is free to be shared on several other platforms. They're not as big? So what? Your right to speak is not "your right to audience the size of your choosing".
