I thought that Godwin's Law was only violated if you use 'that is something Hitler would say' as part of your argument.  I this case it's simply talking about statues of  the man, although it's a bit extreme given that the Nazis were (despite what we see today) indisputably awful.

But that aside, a better comparison would be to say you don't see statues of Rommel or Manstein the so-called 'good' Germans who were merely soldiers.
