I think the point is that to avoid promoting, or appearing to promote Nazi ideology it’s safest to stick with the Penis Swastika on the forehead and/or bike wheels.
That's my point, reclaiming ideology is to be encouraged. If we don't do it in day to day life, when does the right time/vehicle arise? I'm hoping the owner of the mad Max bike isn't some right wing nut job, whose aim is to piss people off.
Maybe, but the same could be said of having a skinhead (which I do), or using the George cross flag (due to it's white pride connotations).
