It's extremely stressful for me as an introvert, but I quietly and patiently explain concepts like due process and open-hearings when I have the opportunity. I stress that everything we do is open to public scrutiny and public comment. I explain that we can't engage on Facebook because it's not an official public forum. I invite people to attend our meetings or read our meeting minutes, but they never do.
Real government is incredibly boring and complicated. Its much more fun to rant and rave about conspiracies on social media.
