>So those chaps making Nazi saultes, chanting "blood and soil", wearing swastikas and so on---what would you call them exactly?
That would be neo-nazism, which is very distinct in nearly all its aspects from the nazism of Hitler's Germany. For example, no nazi had a tribal uniform consisting of a shaven head, a pilot jacket, jackboots, and camo pants. None of them chanted "blood and soil". None of them wore swastikas -- that's a reference to Hitler's Germany, a sad romanticization of Hitler who (as we all know) lost the war and committed suicide.
Each of its aspects (white supremacy, racism, authoritarianism, totalitarianism, violence for violence's sake, dismantling of the separation of powers, opposition to liberal democracy -- I could go on for quite a while longer!) is subject to scathing critique, which people such as yourself will fastidiously disregard because it applies to you in all but symbology. Worse, your obsessive focus on neo-nazi symbols conceals fascism as it appears in e.g. various nations' secret police, private security companies, and the internal security departments of any corporation large enough to have one. One would be readily excused for alleging that you're doing the fascists' work, distracting the rest of us from undermining the fascist strongholds.
Opposition to fascism means opposition to "those chaps", and also to you. Because you, in a nutshell, suck.
