Interesting case law - it does seem to fit the public forum of the internet. On the other hand - does this mean that Liberals can start posting whatever they want on Free Republic?
Not trying to be snarky - but it would seem to go both ways. Perhaps that is why they are trying to go after them with the anti-trust laws, rather than a free speech issue?
But again - I really like your two examples, and will have to try to remember them.
No. There were specific elements involved to be considered a public forum. In the case of the mall, they had government offices set up (Military recruiters) and allowed various community events to be held there. Facebook, YouTube and Twitter do that, as well as allowing cities and politicians to “set up shop”. To compare; Facebook has Marketplace, pages for military, various groups, reunion pages, etc. My city has a YouTube channel and Twitter account. So these really have become the new town square.
