As for this policy, I agree with @Mr. Deez. I am not a fan and would not do it if I was in charge. That said, we do separate kids from parents that commit crimes. I would not choose this policy, but it also is not out of the ordinary. Luckily, I did not vote for Trump so I do not own any of it anyway.
I also agree with Deez and Prodigal that the sinful misuse of scruptire by the left needs to stop.
And I'd like to see somebody on the Left propose a solution that isn't "don't enforce the immigration laws."
