It depends what you mean by "discuss."

Do you mean, go on live TV news program and tell a bunch of half-truths such that people walk away with with the wrong impression? Do you mean, two people chatting in a forum?

Similarly, should Facebook be able to promote blatantly false information? Not pen it mind you, but "simply link?" -- at what point are Facebook's (and YouTube's, etc) algorithms responsible for curating and disseminating information, and why would I think that free speech laws should apply in that scenario?

So yeah, I can throw up a smoke screen of questions to ask, but I still think overall the vector is positive, not negative.
