The ault-right, white supremacy, white-nationalist demonstration was a very high-profile display of organized hate.  To simply "watch" it would be to give tacit approval to it. 

 I, about two years ago, was at a friend's house when a buddy of his came by and immediately launched into an attack on President Obama, calling him a "stupid N$#$%".  I could have "ignored" it.  I didn't and confronted him saying "I won't attempt to change your obvious racial prejudice.  But I will ask you to please in my presence don't use the term "N#@#$$%".  I wasn't about to accept and, thereby, give tacit approval to his use of the racial epithet.

 IMO, simply watching the hateful demonstration by these racist groups would amout to that same tacit approval.  I honor those to stood up against that racism and hate.  Gary Crum
