Does one have to be an iconoclast or revolutionary these days to be validly left? I consider myself to be left of center, and very much in favor of progressive policies.
However I find myself being disagreed with quite often, mostly for not advocating or cheering violence, "by any means possible" change, or revolutionary tactics. It would seem that I'm not viewed as authentically holding my view unless I advocate extreme, violent, or radical action to accomplish it.
Those seem like two different things to me.
Edit: TO COMMUNISTS,ANARCHISTS, OR ANYONE ELSE CALLING FOR THE OVERTHROW OF SOCIETY
if you agree with the aims of revolutionaries (a more just society) but disagree with their methods (violent revolution) then you need to prove your method is at least as effective as theirs
thus far, no such evidence exists. all societal progress has come at the expense of bloodshed. perhaps you'll be the one to change that, but i very sincerely doubt it.
I make one "sort of" exception for Czechoslovakia. I regard it as the only time a country became socialist by voting on it, but they had to do a coup with the implicit threat of violence to enforce the new government. The communists won a plurality in 1946 and had a coalition government. Fearing that they'd lose power, they began stacking the cops and courts with ideological communists. This fear turned out to be true after the liberal parties kept doing sneaky tactics to undermine the socialists. So in 1948 the communists had a coup to consolidate power and ally with the USSR.
And I know this wasn't "bloodless" or "civil" since this all happened in the shadow of WW2.

OP would do well to pay attention to this bit in particular as (a version of) this basic framework is also how civil rights groups like the suffragettes and the err civil rights movement progressed their struggles. MLK et al were able to be nonviolent because the implicit threat of more radical black nationalist groups existed. without the backing of force nonviolent protest is easy to ignore by those in power, as we've seen with every left-leaning protest movement since the collapse of the USSR
