Interesting post, and I appreciate the thought that went into it, though I disagree. Actually Buchanan is not against immigration but wants it controlled in a way that protects our American Way. I think you bring up the diversity argument as if diversity has some utility. Diversity is a neutral concept, neither good nor bad in and of itself. What matters is truth. And a diversity that is against truth is bad. In other words, immigrants who despise our laws and social institutions should not be here.
Of course immigration policy is only one of the topics of this book. What do you think of the others like the liberal assault on our children and social institutions?
I think good parenting is irreplacable. I see a real liberal lean in the schools today and when I went. Some left wing causes are taught, it is true. However, I ended up Libertarian, something many left wingers hate more than they hate conservatives. I think the parental influence is much more than the schools. I say teach your kids to process the input and determine their own truth. I don't lament public schools. I know they have done fine for me.
