Politically correct views on race and an unwillingness to accept empirical realities which don’t dovetail with cultural relativism
This refrain of calling us anti Semites who oppose Neos is no different than race baiting
A lot of libertarian/paleoconservative criticisms of neoconservatism focus largely on foreign policy. Certainly the neoconservative obsession with world democracy and nation building has been bad news, but that's the tip of the iceberg when it comes to ways they've corrupted the GOP and movement conservatism.
One of their major corruptions of movement conservatism was making LBJ Great Society welfare statism the norm among the GOP establishment. Bush's "compassionate conservatism" (i.e. liberalism with some mealy-mouthed conservative rhetoric for sugarcoat) was the most obvious example.
Their other main corruption was giving the GOP its own version of political correctness and multiculturalism. All neocon-approved candidates support amnesty for illegals and liberal immigration policies.
“The offensives of radicalism have driven vast herds of liberals across the border into our territories. These refugees now speak in our name, but the language they speak is the same one they always spoke...Our estate has been taken over by an imposter, just as we were about to inherit”
-Clyde Wilson, commenting on neoconservatives crowding out traditional conservatives and replacing them with 1960s Cold War liberalism.
