The ACTUAL complaint is that people demand an AUDIENCE - they want to be able to broadcast their views to the largest number of people possible.
Nobody in the US is being "quashed" - you can run your own website, print your own newsletter, and nobody is going to kick down your door or send you to a re-education camp. Like I said, Nazis run their own websites, and the Taliban is on Twitter. Nobody here is being "silenced" because they can't grab the microphone - nobody's owed a microphone in the first place.
It's not even "relative privation" - nobody has a God given right to...Facebook. People serious about their causes run their own websites - they don't immediately start whinging because they've been booted from Reddit.
