Just to be clear. The “They” coming for the Facebook posts is Mark Zuckerberg, owner of Facebook.

Give me your car. I want to key some stuff into the side of it. If you don’t you’re censoring me.

Facebook operates in California. It’s users are - by Facebook provided user agreement- bound in their relationship with Facebook by California laws.

Now, the constitution of California provides positive right of speech to it’s citizens: Every person may freely speak, write and publish his or her sentiments on all subjects, being responsible for the abuse of this right. See this dot here? no exception for Zuckerbergs. Or your car.

Then, there is courts’ interpretation of this right. It was as following (by memory): if you created a public forum, then you can’t remove people from it for their speech contents only . That’s why California malls can’t remove beggars soliciting money (you car is ok, it’s not a public forum).

Now, as in now, California becomes a one-party state (feels like home, sometimes). The same Supreme Court (but with nowadays judges) decides: is Facebook a public forum? You can guess the answer.

So you agree. I can carve a message into the side your car, and there’s nothing you can do about it.

Nice. I’ve got my knife. Let’s meet up! Afterwards, we’ll swing by the television station and make them broadcast us live, free of charge or control, a six hour lecture about our novel interpretation constitutional law.

How do you fit 4 billion people in your car?

I don’t. I censor them.

That must be a very big car to have enough space for 4 billion people to write whatever they want on it.

They don’t. I censor them

Yeah but you'd need to have enough space for them to write if they want to.

Otherwise you'd be making an argument in bad faith.

They can write small.

Also, since you seem to be new I'll let you know. This isn't bad faith. It's reductio ad absurdum.

So your argument on why facebook with 4 billion users should ban whatever it likes on its platform is that a car that can fit more a dozen people shouldn't be vandalized.

Yes, I can see why your argument is absurd.

No. They’re both private property.

So were people.

I thought we were talking about government compelled speech.
