Yeah, I second dot's comments.
It's hard to take the question seriously with a capital "V" for violent, and "their" for "there", and "through" for "throw".
And the attempt to quantify the unquantifiable.
"violence", "zealousness" and "revolutionary" are not synonymous, at least in my book.
It seems to me that an anarchist, by definition, is politically extreme. Many people I know think I'm a "wacko", despite the fact I've never thrown a firebomb.
