Decades of  photos and videos of neo-Nazis always reveal the same stupid young guys, long on brawn and short on brains, weak characters who seek strength in the thuggish mob. It will always be that way since no mature and intelligent person would succumb to such hateful idiocy, or make excuses for it, not even online.  
Trump's reluctance to promptly denounce the racist goons indicates the obvious ugly truth -- they are useful to him and his team, a significant part of his backward base. Waiting for moral leadership from the most unfit President to ever foul the White House is as futile as waiting for Godot. But Trump is the cynical narcissist he always was -- the real culprits are the gullible creatures who voted him in, and emboldened the worst among them, and set fire to their fragile society. Still they imagine themselves to be great patriots even as they ensure the decline of their beloved nation.
