Why do skinheads from USA and UK salute Hitler (with the Nazi salute) and use the swastika to represent?

To represent their heritage? both UK and USA and many allies fought side by side to eradicate the plague that was the nazi army. but in the US UK RUSS there are skinheads that wear nazi flags and salute with the nazi salute, even though their families died fought and killed nazis to keep them away from history.
