Personally, I'd apply a completely different property/rule on them. If they're open to the public, and they're used for debate/dissemination of data to willing individuals, then they are not allowed to restrict any speech that doesn't violate any existing laws.

That still leaves plenty of room for the removal/censorship of violent videos, copyright-violating videos, and content with outright calls to violence. Honestly, I've seen a ridiculous amount of the above three examples on all platforms to come to the conclusion that it's both impossible to police such content properly, and that the attempts at classifying content with political speech under the same umbrella is just silencing/censorship rather than it just being a matter of consistency.
