What happened before was wrong. What is happening now is worse, and it got more of the public's attention.
Obama's administration was quietly murdering people without trials in a country we aren't at war with from drones. I fail to see how a temporary immigration ban is "worse" other than the "out of sight, out of mind" effect that applies to those exterminated by drones.
You're making a false equivalence in the first place, suggesting that all Trump is doing is these bans. He's already greenlit a military raid, and children and other noncombatants died in it.

5 of the 7 countries on the visa list are currently being bombed by the US [0].
It's no surprise then that these countries made it on to the Obama administration's list of countries that are sources of terror, which was used as the basis for Trump's visa ban.
From a security perspective it's difficult to argue that countries you are currently bombing won't have people trying to enter the U.S. looking for payback.

People are angry at Trump for the visa ban, but it would never have come to that if not for the destabilizing actions of previous U.S. administrations.
I chuckled pretty hard at this one, imagining a DJI Phantom filming a wedding. Why not call it what it is, "bombing weddings" - the focus is on what the aircraft was doing, whether it was piloted remotely or locally shouldn't matter in the slightest.
No, no they weren't. However it was always pretty apparent that the administration took death of civilians seriously and did all it could to minimise it. That doesn't mean that there weren't screw-ups.
What seems to me, like an outside observer, is that Obama's orders didn't ruin lives of Americans. Unlike these.
And what about Operation Haymaker [1], showing that the intended target consisted of only about ~10% of the total deaths from drone bombings? How can there be any certainty at all about civilian death tolls in massively war-torn, chaotic environments? I personally don't trust the Obama administration's numbers, which are not all that good in the first place.

There were in fact people and organisations who spoke up when Obama was droning schools, hospitals, wedings and funerals.
They do exist. People just chose not to listen.
