Sometimes technically correct isn't correct enough or good enough. The symbol was - in large parts of the world - tainted by the Nazis. By Germans (I'm one).
Sorry for Buddhists that suffer in Europe, but I am a supporter of the ban of this symbol (and lots of other speech, Free Speech is a different concept from elsewhere).
This definitely is a case where use and intent should matter.
I agree with making the reverence of a /Nazi/ symbol something to censor for the public good.
However, use in a historically accurate context? Or even an alternate history, either of which should present it as a symbol being used to spearhead hate and atrocities? I feel like that is a truthful non-worshiping view that should be retained.
Uses outside of that context, such as the symbol's older geometric and religious meanings (probably identifiable by their lack of historically / physically WW-II ties) should be fine.
