I think that is where our differences in thinking are:

I was thinking about modern nazis, which are way more laissez-faire than the “original” (at least where I live). At the same time I would argue it is not very important how a belief evolved if you are talking e.g. current party programs or policy. Sure it can be important for research, but it is only of secondary importance for “applied politics” if the result at the end is the same.
