“Pluralists believe that culture mixing has always been and should be the human condition. All cultures define and renew themselves through encounter. A pure culture is a dead culture while an amalgam culture is a creative culture.”
In the argument between "us" (the cosmopolitans, the pluralists) and "them" (the identitarians, the #nationalconservatism crowd, the separatists), has it exactly right. I would not have anyone "tend our cultural garden."
