Demystify such nonsense
Except it's not, or it couldn't have continued to radicalize people to this very day.
There may be books which radicalise people. But I'm fairly sure Mein Kampf is not one of them.
Like the bible people mostly know the parts of it that fit their own agenda.
And don’t underestimate the effect it has if you are forced to read a book in school from front to back and write essays about it.
