Who here on the Chatter has truly taken part in a street walking, sign carrying, screaming slogans protest?

What was the cause?

Nope.

(65 years of no street walking, sign carrying, screaming slogans protest)

Took part in a "Tunnel of Pride" lineup from our high school gym to the parking lot when our high school team that my son played on went to the State Championship in basketball. I also held a sign.

I did the Climate March here a few years back. It was hilarious and entertaining.

Also Stand Up for Steel in DC while in high school, early 2000s.

Negative. Can't see myself ever joining a protest. 

I ran afoul of a group of Lyndon Larouchies at O'Hare Airport back ini 1986.  Does that count?
