there are several alternatives to "right"

...while I’m not entirely sure of everything the alt-right is (it’s a rather amorphous phenomenon) it is not the KKK and neo-Nazis. The most that can truthfully be said is that ‘alt-right’ serves as a recent flag of convenience to which some old-fashioned white supremacists are busily trying to attach themselves.

Also, the alt-right is not Donald Trump and his Trumpkins, either...

The defining characteristic of the alt-right is, really, corrosive snarkiness... mordantly nasty but unserious.

..part of what is going on here is a visceral rejection of politically-correct leftism, one which deliberately inverts its premises. The griefers pose as racists and misogynists because they think it’s the most oppositional stance they can take to bullies and rage-mobbers who position themselves as anti-racists and feminists...

Whether the alt-right even exists in any meaningful sense is questionable... it has the aspect of a hoax (or a linked collection of hoaxes) being worked by 4chan griefers... who have noticed how readily the mainstream media buys inflated right-wing-conspiracy narratives and are working this one for the lulz. There’s no actual mass movement behind their posturing, unless you think a thousand or so basement-dwelling otaku are a mass movement.

..the alt-right looms largest in the minds of self-panickers who project their fears on it. And of course in the minds of Hillary Clinton’s hangers-on, who would rather attribute her loss to a shadowy evil conspiracy than to a weak candidate and a plain-old bungled campaign.

I’m worried, however, that that the alt-right may not remain a loose-knit collection of hoaxes – that the self-panickers are actually creating what they fear.

For there is a deep vein of anti-establishment anger out there (see Donald Trump, election of). The alt-right (to the limited and conditional extent it now exists) could capture that anger, and its provocateurs are doing their best to make you think it already has, but they’re scamming you – they’re f*****g with your head. The entire on-line ‘alt-right’ probably musters fewer people than the Trumpster’s last victory rally.

It’s a kind of dark-side Discordian hack in progress, and I’m concerned that it might succeed... If you keep [hyping it], the vast majority of the rootless and disaffected who have never heard of it might decide there’s a strong horse there and sign on.
