With a lib, there are unintended consequences.
they are ALWATS present.
Libs really have no interest in the actual outcomes of the policies they advocate.
As far as they are concerned, once the policy is advocated for and implemented, the goal has been reached.
They are now officially a “good person” for advocating the policy.
Telling them of the failures of that policy is a personal attack on their righteousness and will not be listened to or tolerated.
