Why can't we have a rational conversation on immigration?

I think one of the reasons is because, at its heart, it's not a discussion about immigration at all. It is the expression of racism now so in vogue and condoned if not ignited by the sitting president.

This isn't about how to assimilate and acculturate, this is about 'keep' em out.' I've lost count of how many times now people have complained that White America is disappearing.
