Agreed, although I don't think it's the talkers vs. the doers; it's the talkers' audiences vs. the doers.
Here's your "somehow": The lack of critical thinking skills in the general population (not new), combined with the power of instant global communication (new).
The lack of critical thinking skills leads people to seek absolutes, simplicity, and swift action in areas where shades of gray, nuance, and care should be called for. Again, nothing new here: mob justice is a well-understood, if regrettable, characteristic of human society.
Instant global communication much more swiftly connects 1) the easily-manipulated with 2) those who lack experience and maturity but who nevertheless possess the gift of persuasion.
In short, I blame the listeners, not the talkers. It would be a Good Thing(tm) if people were generally more skeptical of everything they heard and read, and even better if they knew how to ask the right questions to resolve that skepticism. It would make it harder for unworthy critics to hold power, and easier for worthy ones to be heard.
Here's another quote, from Joseph de Maistre: "Every nation gets the government it deserves." A similar thing could be said for culture and civil society.
