No one is saying you can't use the term racism. That's a clear non-sequitur. The point is to use the term sparingly and in the appropriate context or it loses its value.
If you can't appreciate the difference between Mosley's black shirts anti-semitism and how this is racism, and a document/manifesto that makes explicitly no reference to race, then I'm at a loss to explain further.
This may help, but if even that doesn't, I think we'll have to agree to disagree
