America is and always has been a nation of immigrants from various cultures, countries, ethnicities and religions.
But first and foremost we feel it's important to bond together based on what we have in common (rather than a patchwork of fiefdoms based on our differences) and consider ourselves Americans.

I disagree that the current threat is "existential"; on the contrary it is a very specific, very real and ongoing threat from extreme fundamentalist Islamic groups like ISIS and its ilk. Their goal is to impose their religious beliefs on the world and replace our way of government and law with sharia law.

That's not going to happen, but these rabid fanatics want to try, and they are a very determined bunch.

Since liberal democratic policies have only resulted in a steady stream of ISIS-inspired Islamic terrorist attacks here in the USA over the last 8 years or so, a lot of us felt it was time for a change in leadership, so we now have the conservatives in
charge of both the presidency and the congress.

I think history will show that this was a wise decision.
