Wow, that's quite the leap. Peacefully attending a public gathering in yellow shirts with printed slogans is nowhere near the violent insurrection perpetrated on Jan 6, 2021. You are approaching "Hitler was a vegan" territory.
"Peacefully attending a public gathering in yellow shirts with printed slogans" is my perfect definition of a protest. You take a message with you, I can read it and decide whether I'm interested in joining your protest or just go on with my life.
My comment's parent called me authoritarian because I said that printing the message on my car would not be acceptable.
