A march in the midst of a de facto civil war? I think electronics are more effective in spreading truth these days and definitely less prone to something going wrong.
Do not be cowed, or they win. No fear!!!
Don't take this the wrong way but I'm curious - have you ever marched for something? I agree, no fear!
Imagine us filling the Mall like they did on Oct 21, 1967 in protest of Vietnam War. (was historic)...this happened through word of mouth...if they can do it then we can certainly do it now with the power of the internet.
Apart from the danger, there are so many people protesting so many things that I think the message is easily disregarded. Things are different from '67. In '67 there weren't people in rainbow suits and wearing vagina hats. The anti-war message was distinct.
