Grammareto, I spent a lot of time at Greenham. I lived at Violet Gate (small). Embrace the Base was amazing, with thousands of women from all walks of life coming together to show what can achieved passively together, this during a time of violent action throughout the miner's strike.
Like so many mothers, I feared for my children's lives (I took them with me) as I believed the only way to have some effect on the nuclear madness was to join others and stand up against the bullies, not by fighting, but by passive methods, including singing!
Would I go on a demo now? I'd go back to Greenham if called for, but agree with Peasblossom, any extremism involved would have me seriously questioning whether my personal beliefs could turn a blind eye to the outcome the protest/demo was achieving.
