This is a very unpopular example, but Timothy McV*gh is probably the most well known example of someone who fought for a cause that in his mind was liberty from government in the united states using asymmetric warfare (he was very troubled by Waco and Ruby Ridge.) Of course, even those who are troubled by those events typically believe it was wrong that innocents such as children died in his acts. But if you really want to know what asymmetric warfare looks like, unfortunately it looks very ugly. The populace doesn't appear to give any indication they endorse the results. I honestly think most people would be very much worried about the legacy their reputation would have; even if they fought for a cause they believed in and avoided collateral damage. The combination of nearly universal social shaming for taking violent action (except when police do it, then it is "valorous"), consolidation of federal power, and the complete ineffectiveness of voting in slowing erosion of rights has been a deadly trifecta for individual rights such as the erosion of fourth and second amendment protections.
