We don't have to look 1,000 years ahead to see the cost of lack of transparency though. False news and obfuscation of his ties to Russia are big parts of what got Trump elected; if there had been transparency about those, it might not have happened. It's connected to privacy--obfuscation is a form of privacy (maybe not in code, but in politics). Clinton's loss of privacy through hacked emails set up a false equivalence. Almost everything in Wikileak's release of the Podesta emails was either nonsense or small potatoes, but it got way more press than Trump's ties to a hostile foreign government--successful Russian maskirovka. That's totally nuts. And Comey's flip-flopping, in the name of transparency, was the coup de grace--there was absolutely nothing there, as he himself admitted after the damage was done. "Transparency" about the wrong things is a distraction and a weapon.
I couldn't agree more about the need for respect and tolerance.
