Part of competing in the current marketplace of ideas isn't just the quality of your idea it's your ability to market it. Whether you particularly like that aspect of our public discourse is irrelevant to the current state. The difference here is that the toolkit of getting your message amplified has a much lower bar to entry now than it did before (a nobody with a good tweet can get their video or soundcloud profile in front of millions of eyes). It's probably the case that we're just seeing a shift in the mix of actors who hold power, but the trend has been towards it being easier for people to enter the fight.
My assumption is that the easier it is for people to participate the more we'll trend towards a steady state where the quality of your ideas and your ability to sell them will be the deciding factor in your reach. As opposed to having a dominant advantage because your [race | social caste | profession | political party] has captured the medium of communication and intellectual production. Unfortunately I think we're seeing those groups (2,3, and 4 primarily) lashing out and trying to maintain their advantage to the general detriment of society.
