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
THIS OBVIOUSLY ISN'T MEANT FOR YOU.
I think you are vastly underestimating the horrors of most pre-revolutionary societies, and probably also overestimating what you describe as oppression in post-revoltionary governments.
On the first point, here's an excerpt from a JFK speech where he describes pre-revolution Cuba:
And JFK was no friend of Castro; he greenlit the Bay of Pigs invasion! Revolutions are born from the most brutal forms of exploitation and violence. Not even the wildest anticommunist propaganda about post-revolution Cuba comes close to the reality of what the revolution replaced.
