I think it's important to give it attention and show the imagery so people realize the real state of white nationalists.  It was in one of the threads here a few months back where there were posters saying there really aren't any white nationalists and that it's just one here or there.  That the rallies have only 8 people showing up.  That it's not a really problem, that Nazi's in America don't really exist.  Well, they do.  And the problem has gotten worse and the assholes emboldened by Trump and his unwillingness quickly condemn such folk. 
I am not claiming that most Trump supporters are Nazi's, I don't believe that to be the case, but I do think many have been willing to turn a blind eye to so many "White Nationalists" supporting Trump and to Trump not telling them he doesn't want their support. McCain, Obama and Bush all told supporters at some point that they were not welcomed when they said outrageous things about "others".  Trump has spoken out only a couple times, and only once a shit-storm ensued from his lack of initial response.  And always with caveats.
These images create indelibility.  That matters.
