A short story: I was visiting a friend when one of his other friends joined us and immediatedly began an anti-Obama rant.  His first words were "that stupid N#$%#$".  I interrupted him and said, "I don't accept racist slurs in my presence.  If you're going to use them, please let me know and I'll leave and come back to visit Bob later."  It was a bit awkward, but he got the message.  IMO, we must all confront racist, hateful speech and action when we hear or see it.  Yes, confront it peacefully, but let the actor(s) know we condemn the action.

Passive acceptance is "tacit agreement."  If the man uses "N$#@#$" in my presence and I say nothing, he can (and likely will) conclude that the term is OK with me.  On a much larger scale, ignoring the celebrations of white supremacy and white nationalism, IMO, constitutes tacit acceptance and agreement.  We must voice our condemnation "loud and clear."
