Suppose I decide to be outraged at something I saw on my local TV news. I hop in my car and drive down to the Station, demanding to appear on camera to present my largely incoherent argument against whatever they broadcasted. Do they mic me up and put me on the air? Probably not. They are far more likely to turn me away and call the police if I refuse to leave.
But what if I whine that my "free speech" has been violated because this TV station will not permit me to use their platform? This won't change their minds. Most reasonable adults would conclude that I am a moron. So why does this change so dramatically when we switch the context from a TV station to a blog, Facebook page, YouTube channel, or something similar?
