It’s all about branding, folks. Apple re-branded itself. The Trump Organization re-branded itself. The Koch Brothers are re-branding itself. What makes you think the Klan wouldn’t re-brand itself?
With that said, I don’t think violence is an effective way to stop their message and I don’t think we should silence them. We legitimatize their voice and cause by silencing them. That’s what they want. Remember Martin Luther King Jr’s work and how people try to silence the civil rights movement? Let them speak and beat them in a debate to make them look crazy.
