There are no good Hitler analogies.
I get that and this is not (IMO) intended to be a hitler analogy.
It is the story of how someone like hitler could come to power.
But you are right, we have trouble analyzing what he did because someone always come out with a "so your saying... is like hitler...he is going to strt a world war... or try to commit genocide..." And that always distracts from the point trying to be made. Regardless, there are very important lessons to be learned.
