They got 43.9% in what Wikipedia marks as "semi-free yet questionable election". Also more correct question IMHO would be "was the NSDAP extreme in 1933?" and the answer is probably "no as much as by today's standards".
Their ideology implied at the very least getting rid of whole populations. They wanted to reset to an imagined ancient culture and rewrote history to justify it. Mostly imagined, anyway - Sparta was the one real example they looked to.
