Skinheads, neo nazi, nationalists,and fascists, what are the difference in these terms in today's Russia?

They all basically agree with one principle which is having an all White country. Skinheads are kinda more gangish and tend to be the most violent of the groups. Neo Nazi, well I belong to the National Socialist Movement, so I guess I would be a Neo Nazi. We believe in the political aspect of what Hitler created. Though the groups you mentioned above may agree on race, they will not all agree about politics always. I do not agree with all the points of National Socialism, but no other group in the US is getting anything done. I hope I answered your question
