We live near Seattle and my wife is active at Seattle based museums and historical groups. We have been attacked by self-righteous liberals at completely unexpected inappropriate nonpolitical occasions and completely unprovoked. And we too have been shocked that people we thought were our friends stood by and said and did nothing. It reminds me of the following graphic when someone you don't even know realizes that you are not a full on leftist retard and goes off.
I think you softly reply “Venezuela...Venezuela and keep repeating it as you turn and walk away....if they try to hinder you well...let one’s level of tolerance vs self defence dictate one’s next actions as you continue to try to walk away!
