Have you ever been part of an in the streets protest? Yep. Right after Kent State. Tear gas and pepper gas.
What is important enough to you to do such a protest? 58,000 dead in Vietnam.
Do you think they work to change anything? If enough people voice their opinion.

I took to the streets to protest the UK joining in the invasion of Iraq. Do street protests make any difference? Hmm. A million people joined the protests (which means that, conservatively, 10,000,000 (or almost a quarter of the adult population) were vehemently opposed to the war). Our government took absolutely no notice whatsoever.

Same as Quiver.
Some of our Government noticed. Blairs greatest opposition at that time came from his own back benches.
Shame he lied to them and us.

When I was in 6th grade, the teachers in my town went on strike. My mother and some friends made signs and we picketed with the teachers. It was a cool experience, but I haven't since.
