He also got a lot of support, it's not like all media and all politicians attacked him. But those attacks also happened, including a person who dreamed herself future chancellor (at least as far as young people are concerned, she can completely forget that now) musing about whether it should even be "allowed", to just point out the list of hardcore failings before an election: https://www.youtube.com/watch?v=wX3Mz8pdFCs
Yes, we are better for Neonazis not being allowed to run around with swastikas, and I agree that many Americans don't quite get that, but there's plenty of dystopian-in-spe bullshit to be found, and that's not even getting started on the UK. At any rate, the laws that forbid displaying swastikas to glorify Nazism etc. weren't just decided nilly-willy, because "obviously" that had to be done. They took that decision seriously and discussed it in-depth, so exactly the opposite for these rationalizations for censorship by self-styled SV shepherds.
