[edit: originally included Stefan Molyneux in my defense but having taken a look it seems he's started putting out much more alt-right content].
Disagreement with the prevailing orthodoxy is one thing - I'd like to hope there's no one here who fails to see the value in honorable, substantive dissent, even from an orthodoxy with which one strongly agrees in general. The trouble with Molyneux is not that he dissents, but that in doing so he fails to display either of those meritable traits.
Alt-right means white nationalist, and it shouldn't be confused with civic nationalism, which is something altogether different.
And if you believe in something "your enemy" also happens to believe in doesn't mean you are on a thin line. The World doesn't work that way, propaganda, especially political does on the other hand.
