As always, there are several different aspects:
- Promoting [Nazi propaganda and misinformation]
- Laughing at [...]
- Analyzing [...]
- Profiting from [...]
Sometimes the difference between "promotion", "laughing at", and "analysis", depends more on the reader's approach, that on the writer's intent.
Then again, sometimes a reader decides they don't want to deal with any of it, which is also respectable.
