Different times, different circumstances, different century...every aspect of your Hitler and KKK analogy is different.

It is not a ban, it does not put people in gas chambers, it does not send people back to Africa...what it does is make sure anyone...anyone...from those specific countries are sincere, truthful, and legally able to enter the USA without being a threat to our country.

Maybe what you want is to open Honolulu International Arport and invite all those to refugees Hawaii?  'Come to Hawaii's paradise...L.A., NYC, Seattle, SFO and other port of entries are are arm pits...Hawaii is the best!" is your calling card?

Or is your thinking that as long as these undocumented refugees do NOT move into the house or camp in the yard next to your home, it is OK by you? 

What does Hitler's and the KKK have to do with this?

Maybe you are reading the wrong story?
