Yes, absolutely I want our government deporting people _at points of border entry_ based on their political beliefs. That shouldn't even be controversial.

If you're into North Korean or Iranian hardliner "Death To America" politics, I sincerely hope that CBP calmly and politely has you gtfo at point of entry and hopefully no later.

Granted, I wouldn't want it to be _these_ political beliefs, but if you're a journalist publicly flying afoul of the political administration of the country you're traveling to, being denied entry is pretty much status quo around the world. It shouldn't be a shock to anyone.
