I am not sure I get your point.
1. This isn't a law. It's Trump's choice.
2. The choice doesn't require the separation of parents and children. Trump has elected to do so.
3. Traditional immigration methods (ie conservative models) haven't worked this way under either Republicans or Democrats.
4. It is obvious to anyone that Trump is being nasty because he can't get his wall into the budget.
5. It is damaging to children, who have done nothing to deserve it. Holding the happiness of children hostage is pure evil.
6. Shucks to your claim that you believe life is sacred. I will remind you you don't give a damn about the lives of children when the abortion debate reappears.
7. Suffer the little children to come unto me. Who the heck said that? Oh yes. It was a man with a compassionate spirit. A person who had nothing in common with the Christian right.
8. The US declaration of independence assigns the right to life, liberty and the pursuit of happiness not just to Americans but to all people. Trump contradicts Jefferson's central justification for US independence.
9. You forgot to bring your long spoon to supper.
