Well, first, I reject both sidesism because Nazism is an ideology that wants me and my friends to die, and denies our very humanity, and my ideology doesn't really want anyone to die, and absolutely does not deny anyone's humanity.

However, under liberal democracy I personally don't believe the wearing of a swastika should be a crime, though I don't mind if people wearing swastikas are rejected from every interaction they attempt to have, denied business everywhere. The simple banning of nazis memorabilia doesn't seem to be doing anything to stop the rise of nazism in Germany so it seems pointless overall. The Germans had their opportunity to actually apply this anti-nazi law when banning the AFD came up, and they failed to act, so it seems the only thing the law is good for is preventing people from playing Wolfenstein.

Under other forms of society I think the wearing of a swastika should result in the ejection of someone from society entirely.
