"We've lost our compassion."
No... we've had our compassion taken for granted. We've been beaten over the head about what we "must do" for every poor person in the world. We've even overridden the rule of law for the sake of your "compassion," and made ourselves poorer in the process. Also, real compassion is voluntary... the last administration FORCED it on us, ignored our own laws, and brought in more of these folks in an effort to swing voter demographics. Now comes the push-back.
In short, screw you. They have to go back. They knew they were here illegally, and that the gravy train might end. They knew this, and gambled that it would continue... they were wrong.
We didn't "do" this to them... they did it to themselves.
