Do you think white supremacists would have more followers if they toned it down a bit?

What i mean is every time you see white supremacists they are spouting fowl language and using phrases like "jew lover" or "race traitor" or other strong sounding stuff. With how idiotic people are led like sheep into doing stupid things, do you think that white supremacists would be more effective in recruiting others if they put a positive spin on their hatred?
