Ep 139 Is being Morally Right better than being Factually Correct

This is a paraphrase of something AOC once said in response to getting some details wrong in her criticism of Trump back in 2019. But I think this is a good representation of what many people in government today believe. That is, their Belief justifies their actions regardless of what other information others would present.
What is the problem with this position? And what might be better?
Just trying to create a subjective starting point for something which is so subjectively confusing.
