I don't buy this all-or-nothing argument. People in the US have tried to ban books, heavy metal music, video games etc. And the idea that we've ONLY survived those attempts because we allow people to fly/wear swastikas is ridiculous on its face.
It's not about swastikas, it's about a hard and fast rule that speech is permitted because speech itself is not directly harmful to anyone or anything.
Humans, of course, respond to speech and frequently do violence, but the speech itself is not the violence (there is an extra step involved).
This "no banning speech" general rule is why it has been largely ineffective when people have tried to ban books, movies, music, or games. It's not the swastikas; those are simply a side effect of the same root cause.
