I'm basing this on the history of combating fascism, which has always required violence to achieve. I said that it was a fact, which was a poor choice of words on my part. What I should have said was that, due to it having always been necessary to use violence against fascism to defeat it, and due to no one that I know of having ever defeated fascism through peaceful means, I'm inclined to believe that violence is necessary to defeat fascism until someone proves otherwise.
