I think it is nothing more than the alinsky tactic to label and demonize and objectify, to get us conservatives on the defensive.
Last time it was NEOCON, and of course racist, sexist, homophobe, and like Alt right it is usually without a clear definition, but the name is just to objectify the enemy of progressives.
Count on the next election to have yet another ‘label’ to have slapped on us.
I have always thought that we could slap a label on the extreme left, like NEOCOM (neo-communist).
Much more truthful, realistic and applicable too than any label they have used on us.
