If I am forced to host your platform/speech/lewd gestures/etc. you're taking away my rights of free speech to not host your platform. No one is taking away access. What they are doing is kicking the drunk ass jerk out of the bar for harassing other people because they were warned to stop being such a dick and they continued on anyways. They can say whatever they want from someplace them own and no one is preventing access to them. They want a bar full of jerks, they can go right ahead and have no rules of decorum.
You're confusing unlimited speech with free speech. There has never been a right to access to all speech. Private conversations happen all the time and no one has a right to listen to those. So again, just because someone owns a billboard doesn't mean they are required to post your message. The courts have been pretty solid on this and it's why the baker won his case against the couple. You cannot force me to advocate for you if I don't believe in it.
This is the mentality of intellectual inquisitive people and needs to be promoted as it's currently under attack.
If I'm running a platform, I have the choice to make it a moderated platform or an unmoderated one. If I make it unmoderated, you can have your "free access to everything". [Edit: At the price of it becoming a cesspool that most people don't want to wallow in.] But if I make it moderated, you don't have the right to make me carry anything on it that I don't want to carry. You don't like it? Go run your own platform, and carry what you like.
And between all these different platforms - some unmoderated, and the moderated ones having a bunch of different standards of what they will and will not allow - people get to freely choose which ones they want to spend time on and contribute content to.
All that can work without the government forcing anybody to do anything.
It's weird you say this because it really seems more like the mentality of people who want a state sponsored megaphone to shout, "Debate me you cowards!" into.
You're welcome to it, but it seems tangential. I certainly am not interested in you telling me how to feel.
