I don't know why that expression is being taken literally. Obviously if you make terroristic threats to the US government you're going to be in trouble no matter where you post. Obviously the context is given by the original submission.

The point is that the attitude I was responding to is extremely entitled. You're not entitled to use Facebook. You're not entitled to post about abortion without a fact check from Facebook, that is up to them. If you don't like it, leave Facebook.

I'm tired of the public square narrative, as if Facebook is the only forum for discussion on the Internet. If Facebook blocks my speech, I can talk about it on Twitter, or Hacker News, or Gab or chan boards (using these as an example), or my own website, or any other number of places for discussion.

Facebook is a private company.
