You can't just say people on the right are admirers of Hitler, just as I can't say people on the left are admirers of Stalin or Castro.
And by the way, The National Socialist (Nazi) Party shared ideals with both the left and right.
The clue is in their name: national(ist) which is a right ideal and socialist which is a left ideal.
Actually, their full name was The National Socialist German Worker's Party.
If the nationalism part weren't included in their ideology, they'd have been considered totally left wing.
In fact, their rise to power was largely due to the German middle class' savings being destroyed by high inflation and Hitler vowed to fix that with socialism (a left ideal).
They actually didn't like capitalism (which is a right ideal).
