Dr. Johnathan Haidt who has done the majority of reviewed and tested research and clinical testing of morality had some pertinent information on this which you probably already know to be true, but in his book "a righteous mind" he innitially concluded the left doesn't understand the right but the right understands the left.
Last year he did a follow up test sample where he got conservatives and liberals to larp as each other while answering moral tests, conservatives were far more accurate determining liberal answers, but liberals, those self described and test prescribed, universally answered questions thinking conservatives care absolutely nothing of fairness or justice that right wingers are complete and utter monsters.
They utterly don't understand us because their comprehension of fairness is extremely flawed and their ideas of Justice are plainly just without basis they have an almost 0% chance to score well on those parts.
Never forget that you feel pity for them, but they have utter malice and contempt because they don't understand you. Liberals are the MOST illiberal.
