What?! What liberal was upset about the Iraqi invasion because of the lack of UN approval? People were against an Iraqi invasion as it was a preemptive use of force against a nation that wasn't harming America under a cloak of being part of a 9/11 military response.
The "nuance" of that distinction is a red herring that actually prevents people from appreciating the full weight of what happened, and set the stage for a complacent populace (and media) to allow the slaughter of thousands of innocent people.
Goodness you have fallen off the rails here, with a strawman and then nonsensical rantings.
And here we are again. Let's ask ourselves about nuance here, shall we? The illegal entry of non-citizens into America is a misdemeanor. It's not even a felony. The American response to acts of illegal immigration has always been a calculated overreaction designed to provoke fear and to punish, not to detain people humanely until they receive due process. No misdemeanor justifies the forcible separation of children from their families and extended internment in camps. When the law says otherwise, the law is wrong.
I suppose I must be wasting my time because you clearly aren't reading anything I am writing.
