There is nothing in nazism that is about unifying the EU, just as there is nothing in right-wing skepticism that is about a superior race.

Thats the point. Just like the fact that the nazis did have a dream of a unified europe also politically doesn't have anything to do with the EU we see today, the fact that some right wing party was started by someone with nazi sympathy does not mean thats why people vote for them today.

I don't know how to make the argument much clearer to you.
