To be fair, the majority of Republicans aren't as extreme as wackjobs like Coulter. That said, there is significant number of fringe Republicans that have much in common with North Korean communists.
- Racist. Fringe conservatives hate immigration because you see their own proud slave owning ancestors didn't immigrate to America. They've been here since the invisible spaghetti monster created them along with the dinosaurs (you know, 6000 years ago). You're only a "real" American if you're white and part of their Christian master plan. Native Indians, Blacks, Arabs, Hispanics, Asians. even non-western European whites... pffff.. all "fake" Americans.
- Super "patriots" whose definition of "patriotism" amounts to demonizing ever other nation on earth. (see above for any exclusions)
- North Korean communists hate religious extremists. Fringe Republicans also hate religious extremists...unless its a religion they approve. God hates fags and non-white folk after all.
- Have a great leader they idolize to point of cult worship. Comrade Bush was never wrong (and never farts).
- Wildly support mass government surveillance like communists. It's particularly ironic when alleged constitution loving fringe Republicans grossly violate the constitution by supporting Orwellian government surveillance. Right to privacy? You must be a terrorist.
- Heavy handed use of force. Endless rhetoric for wars against this nation or that. Hey lets invade another country for non-existent nukes... while simultaneously wanting to expand already one of the largest stockpiles of thermonuclear weapons in the world. The invisible space leprechaun said is OK for Americans to have WMDs.
- Support use of torture.. or as communists in North Korea like to call it "enhanced interrogation". Feeding prisoners through their anus is a "medical procedure".
- Communists and fringe Republicans both claim to support democracy and their citizens , -- while simultaneously supporting policies that promote extreme inequality.
etc.
