If you follow a Nazi, does that make you a nazi? There are many people out there with strong opinions on immigration, gay marriage, Christian persecution, etc. and they do not want to be labelled a Nazi...because they truly are not.
But of the 13 million Germans who served in the Nazi army, how many of them never really considered themselves Nazis? How many of them might have agreed with the Nazis on a couple policies, but didn't agree with genocide and war? Nobody knows and nobody cares because if you follow Nazis that makes you a Nazi too.
Have you heard that old saying "If there’s a Nazi at the table and 10 other people sitting there talking to him, you got a table with 11 Nazis." If you replace "table" with "picnic" then you have to decide whether you want to be at the picnic with these folk.
