It depends on whom they talk to. Adult informed people will easily ignore their nonsense, while youngsters will very often be attracted by the Nazi/Fascist false sense of strength because in their still young minds aggressiveness equals strength.
Fascism is coming back in some parts of Europe and we won't get rid of it by simply asking politely to go away.
Ideas like fascism rarely spread because they’re better. They’re simpler which makes them more appealing. Better ideas also tend to be less appealing on the face of things because they’re more complex.
But that doesn't explain its popularity; other ideas are simpler than fascism and don't spread.
Fascist leaders gain an audience because they address concerns which their opponents (liberal globalists) won't bring up, for fear of alienating their own support base. Fascism may not be the right solution, but dismissing its supporters as too simple-minded to understand complex ideas doesn't help advance a better alternative.
Unfortunately its not just "youngsters" who lack the critical thinking skills and/or intelligence to be influenced by "nonsense". What these laws are really about are trying to ensure that easily-influenced people are only influenced by government nonsense, rather than nonsense that the government frowns upon. The bottom line is, that to have and maintain a decent society, you need a population that is (to a large degree) informed, aware, and possessing of critical thinking skills. This is true whether you are talking about criminalizing frowned-upon speech or the "fake news" phenomenon that has been popularized here in the United States as of late. The core problem is that those at the pinnacle of our society (the permanent overclass of the ultrawealthy, oligarchs and intelligentsia that control governments and other levers of power) want to have it both ways. They want a largely ignorant, easily-influenced populace that they can control and influence while at the same time having a populace that is immune to ideas that are frowned-upon (by them). Since this isn't possible, their only alternative is to try to silence the "nonsense" that is frowned upon. We see this in Germany via this hate speech laws (which are largely aimed at stifling dissent over their massive influx of North African/Middle East immigrants and the resulting problems), and in the United States via Russiagate (which is an attempt to paint those who oppose the CIA/DC/NATO narrative as traitors or Russian agents [see the treatment of Jill Stein, Ron Paul, or the WaPo's Propornot article as examples]).
