The ultimate disrespect was during the demonstrations against the inaugural when a cell phone video caught an anti-Trump female protester actually LIGHTING ON FIRE the hair of another female who was a Trump supporter.
It was in a crowd of otherwise peaceful Americans, check out the frame at 1:14 into this video.
This evil act was emblematic of how the leftist protesters and anarchists want to deal with anyone who disagrees with them. They light us on fire and then disappear into the crowd of their peers.
If we did not have the political system we have, a Republic that guards against the tyrrany of the majority, we would be at real war here at home.
