What is the difference between Asatru, Odinism, and Irminen, am I missing any?

What other groups are counted as Heathens and what makes them Heathens rather than Pagans?

What are the [supposed] links between Heathenism, Norse based faiths, and racism or is this just myth?

*hands up* No Heathenism is not a branch of Paganism I know much, or anything, about.
Update: No, not heathen as an insult, those who actually call themselves heathens such as Asatru.

I know about pantheism and polytheism within Paganism, I'm curious however about what makes them 'heathen' and about various heathen paths.
