"So why isn't Saudi Arabia on the banned list?"

Because it has a functioning government?

"But if you've been paying any attention to the news whatsoever, the ban isn't just being applied to people from those countries."

How is Trump responsible for the OVER application of his EO? Individual DHS and border security representatives still have lots of sway to exercise their own prejudices. Let's hold the actual bigots responsible for bigoted screening.

It was 90 days, in writing, in the EO, and affected about 5% of the Islamic population of the world. You're making a mountain out of a molehill.
