‘alt-Right’ has been around for a year or two that I know of. Maybe longer. Somewhat of a self-identifier for a youthful group on the right that holds decidedly un-PC ideas on forbidden topics like race. ‘Cuckservative’ was a neologism that they popularized awhile back.
The PC-obedient right regards them as a bigger threat to mankind than Hillary and Obama, so both Hillary and neverTrump will be claiming that Trump meets them for secret midnight cross burnings as they stiff-arm salute a swastika.
I have ALWAYS been against PCism and refuse to EVER be PC! Some little snowflakes, here, can't stand that I am blunt, but that's their problem. *snicker*
