absolute refusal - to learn.
Sorry, you are wrong; it is not that they (liberals) refuse to learn it is that they CANNOT BE WRONG! I have seen them in govt and had to deal with them over me in the private sector. No matter how badly the idea fails it is not a bad idea; we just didn’t do enough of it!
Or some REPUBLICAN stopped them from doing it 100% as planned.
That’s the usual excuse.
