The vast, vast, vast majority of protestors are not engaging in any acts that could be considered terrorism. The OP linked article is about peaceful protests. Your parent comment was “that’ll show the minimum wage slaves.”
So should no one protest peacefully because a handful of people have committed acts of violence?
I suppose that’s the risk we all run in Trumps America.
Perhaps if the leaders at the very top weren’t sociopaths who provoke critics, scapegoat immigrants and encourage the sale of firearms to every American, then we could all be living in a peaceful nation without the fear of a Molotov crashing through the window of a Tesla dealership at any given time.
