The issue is defining terrorism. If someone who is pro white commits a crime it is labeled a white nationalist crime. If a black man who liked BLM on Facebook shoots a white guy is it a black terror attack? If a white guy attended a pro white rally and shot a black man two years later it would be called terrorism. Yet a black man who has attended a blm riot two years before killing a white person isn't a terrorist.

If someone pro white commits a crime their politics is always mentioned. If a Democrat or republican commits a crime their politics isn't mentioned unless they were a full time activist or had published a manifesto right before committing their crime.
