Here is another good synopsis.
Your link would be pertinent if I denied there are two strains of Alt-righters. But I don’t. Like the very knowledgeable Paul Watson, I agree there are two groups going by the same name. This is a fact.
If you doubt it, do this. Go onto r/The_Donald and start a thread. Use it to tell them they aren’t Alt-right.
They’ll set you straight very, very quickly. It would be priceless to see!
