There was a time in history when diversity helped to strengthen America. That was back when our immigrants wanted to--and did--assimilate. Now they're encouraged to maintain their own identities, their loyalty to whatever land they left behind. It's the lack of assimilation that hurts. Might this explain why the current Dems discourage assimilation?
I'm just a little surprised that people rushing to escape their native lands are willing to be loyal to those same failed societies. And yes, it will doom America as we know it.
