"a peaceful movement". Ok. Unilaterally disarming seems like a dubious move to me.
I don't think protests where you just stand around and chant are especially effective. Maybe in 1950 when seeing people get firehosed was shocking, but the world is different today. Media is captured by the wealthy and most people don't care.
This is a good point. Seeing other people get onto the street can motivate people who weren't feeling enthusiastic.
But I do worry that protests will fizzle out and be, as you say, an ending point. Maybe they won't be.
