yes, a few
When i was a kid i have a vague memory of protesting some KKK march in our small Connecticut town, but i think maybe i was jsut mad about it with my friends, not an organized thing.
in college- i protested the local town's blanket decision to take away our right, as residents (there nine months a year or more in some cases) to vote.
I made buttons flyers, and marched.*
After, i was in the NYC protest against the Iraq War, and i also took part in the march against the RNC in 2004.
I've also helped out in some minor ways with more local protests, against the building of a Newer poer plant and agaistn real estate moguls and their mogulish *****ebaggery.
And now i agree with Wilh, pretty much its useless. Esp, when you consideer the way the media can spin protesters to look liek "angry mobs". The real point is- protest if you want- but then you have to also DO something tangible. That's more what the deal was with the localized protests. you have to start small, but you don't have to stop hollering at the masses if you don't want.
*in this case we actually , together, did get back our right to vote. this was in 1996.
