Meanwhile, no one called Obama a hater or racist while deportations and detentions were up under his administration. This managed to go mostly unnoticed by protesters in the streets or either it represents a double-standard.
Exactly! And that could be because he was concentrating his deportation efforts on criminals while going out of his way for children of immigrants who have known no home by the US. And in doing that, he still managed to deport more people in the US illegally than anyone else. So maybe it isn't the deportations or excluding people that is causing concern.
Sadly, the ban is a knee jerk reaction to an emergency that doesn't exist. Trump did not consult people who actually understand how the immigration system works, instead he made a purely political decision and put it into action purely with his political team. The same way Chavez made economic policy. And with the same mass unintended consequences.
Obama excluded Iraqi immigrants when an actual problem was identified that allowed several undesirable people to slip through. Everyone had to be re-vetted to make sure that whole was plugged and new applications were frozen until the existing pool was cleared. No great outcry, because it was done for an actual reason and wasn't in a fake fear induced panic.
Rather we set up a situation where engineers who have studied and lived in the US for over a decade working for the most advanced companies in the world (Boeing, Intel, SpaceX) who were overseas for work and now can't come back to the US for an undetermined period of time because they are from a "suspect country." Students, college professors, and researchers. Where women and children who have been vetted by a dozen agencies over 4 years can't come because we are afraid of them.
Immigration/refugee quotas isn't the issue. Exclude Mexicans. Cut the number of refugees we allow in. You won, you get to do that. But lets do it in an orderly fashion that doesn't make us look like panicked children afraid of tragic yet remote possibilities. Team Trump hasn't come up with a plan to "fix" the system, because no one can point out what isn't working to begin with.
The desire to exclude the tired, poor and huddled masses is an entirely different issue. By all means, tell me you can't bake a cake for the gays while pounding your bible and then quietly set that book down and tell me how taking care of the downtrodden isn't our problem. Theocracy isn't so popular when it requires action that you don't personally like.
