Is wikipedia right to claim that Adolf Hitler is a liberal protestant based on a historical approach to Jesus?

He was officially Catholic with unorthodox beliefs about Jesus. He was a great admirer of Martin Luther (for his vile anti-semitism, there's an evil man everyone forgets was evil) so I guess that's where they got the Lutheran thing from, but Hitler was not unorthodox enough for the RCC to ex-communicate him, even now.
