Political violence is not a good thing, and I absolutely can not support it when violence is not threatened or happening first.
Beating nazis isn't "political violence" in the very same way that shooting a rapist isn't "murdering your sister's lover". Monsters behaving as monsters, nothing "political" about it.
Millions of American GIs - and British SAS - would strongly disagree with your (apparent?) stance on nazism. When one chooses to don that symbol & adopt those 'ideals', he/she forfeits their humanity....
