Everyone knows it was a Nazi Salute.

Nazi's just denying it because 1) they are not quite at the point where they can sieg heil while marching down mainstreet just yet and 2) because it amuses them to see the left try to desperately convince them it was a nazi salute.

All your desperate justification, facts, evidence, etc?

It wont make a nazi not a nazi.

but it will amuse them, and exhaust you.

Its time to stop using words against nazis, and go back to using forms are communication that carry a more physical finality to their arguments.
