It is none of my business; still, I want to say that Americans should let their president get on with his job!
You can't have a situation where a high level public servant openly defies the system and refuses to implement the policy of the incumbent government. That will cause the government, any government, to collapse. Perhaps that's just what those who are opposed to Trump want to see happen.
In the circumstance, it was right of Trump to promptly give Sally Yates the sack to show who is boss.
Just because you did not vote for Trump, you still have to accept the outcome of the presidential election. You are part of the electoral system that, for better or the worse, saw Trump become the president.
Immigration is the prerogative of a state. Imagine that any one and everyone has the right of entry into any country! It is for the government of the day to set a country's immigration policy or its tenor.
The trouble with the west is that they always want to appear being politically correct, irrespective whether that might be detrimental. Perhaps being politically correct makes them feel good. Perhaps not appearing to look like the bad guys makes them feel like heroes.
If only, if only......
That said, I am no supporter of Trump! Trump might or might not be a disaster for America or for the world.
We just feel that the rest of the world can deal with him.
There is only so much bullying, confrontation or trade wars that Trump can do without also putting the America and its people he declares he works for fervently, to mutual harm.

By the way, if you want to be politically correct and consistent, you should also raise heaven and hell over the long standing blanket bans by many nations, including that of Bolehland's, against citizens of Israel from entering their countries. How is it politically correct that these countries can ban certain people from entry while it is politically wrong for America to do so, especially when Trump's ban is occasioned by the threat that unregulated flow of immigrants from those countries poses to America's own security?
