Well, I am a heathen, but not Asatru. Asatru speaks specifically of the Neo-pagan adaptation of the elder Norse heathen faith. It is heavily influenced by Icelandic practices and social structure. There are many variations of heathen religion (Asatru, Th?odish Geleafa, Irminism, Odinism, Norse Wicca, etc.) because no single religious practice can meet the needs of all heathens.
