Depends if that person fully knows what the national socialist party was about.
Many German people during the time of the national socialist's didn't know entirely what they had planned.
A pretty good personal example I am aware of is the other year when my secondary school decided it would try to promote people's attention to politics. (Which is actually really dodgy for a school, since they legally have to remain neutral politically and can't force opinion on you.)
Anyway, we had the UK General Election, and alongside it our school let a few people make a fake political party (but could mimic real life parties, or take up their role), including making a manifesto, giving talks and making posters and things.
There were a couple of people who did real life parties, like one person did the Labour party (He was all on his own), a group did the Green party, another group did a more right-wing conservative style (Although not actually the Conservative party), and then there were a couple of other ones.
But the big one in there, which was ran by a few students from the highest year in the school, ran a party that they called the PPP, which had a safe meaning, being the Pilton'sPeopleParty.
The PPP was a joke in referencing the kool kids klub. And the logo they came up with was 4 P's organised in such a way, overlaying each other, as to make a Swastika.
They then chose some of the most widely agreeable political views that the national socialist party had and used those. They even, in their manifesto, in small text used some of the worse sides of the national socialist party. Although they hardly said the would kill all Jews, they certainly made reference to removing all those not fit in their eyes.
And then in the campaigning, they even had some national socialist-Propoganda style posters, and many others which they slapped everywhere, and even sabotaged (ripped down) some of the other parties posters.
So, most of the school was honestly truly ignorant to the entire thing. They just went and voted in this fake voting booth, for the party they wanted. And the national socialist party, due to the way they advertised themselves, managed to come out with a landslide victory, at roughly 65% of all votes.
So, anyway, three students managed to convince most of an entire school to vote for the national socialist Party.
What I'm most surprised about is that the teachers didn't stop them.
But I suppose once they let them go through with it, they couldn't stop them without interfering with their political views.
Just goes to show how easy it can be to brainwash some people. Put up a fake disguise, have some things that sound good, and you can get most people to join you. Just hide your dirtier side for when you're in a position of great power.
Also, some people are stupid and think it's edgy to like the national socialist's.
They're like to get beaten up.
