I believe I related my experience last year or so, when our local BLM protestors surrounded my vehicle, aggressively approached it, and would not let me proceed. They were doing this to pretty much every vehicle trying to progress through the main intersection in our village. In their discussions afterwards, they freely admitted that they wanted us "to feel the same kind of fear that others do"... They are lucky that ended well for them.
I don't care what political persuasion someone is, once they start engaging in terrorism, unlawful detainment, kidnapping, and what-have-you, well....play stupid games, you may win stupid prizes.
