Neo-Nazis are not anti-capitalist. Their hero Hitler got along extremely well with the big German capitalists of his time. They prospered under the Nazis, unless they were Jewish of course.
Fundamentalists would have much more difficulty identifying with communists since they are against religion.
Neo-nazis aren't obsessed with aryanism. The prime difference between neo-nazis and nazis is that neo-nazis have now substituted white for Aryan when making their rants. Thus you can now find neo-nazis from a broad variety of formerly scorned groups such as Poles.
That said, you can find communist and neo-nazi groups over lapping with Christian groups, but the fundamentalist tend toward the neo-nazis.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
