My sense of this is that you can feel inwardly there is something wrong with liberal thinking, that their is something wrong about their morality, that they are harsh and judgmental and quick to condemn other people who fall outside of their herd generated and stereotypical thinking. If this sounds like something that might apply to you I would say you are right. But not even a liberal like myself, of a progressive and hopefully not so authoritarian demeanor, can offer them advice in this manor. They, like conservatives generally, are in love with their rage. The mistake that you make, therefore and also just my opinion, is that when you or anybody for that matter tries to argue them out of that rage by challenging the facts upon which that rage is based, you will fail miserably, because what is wrong with their thinking isn't the logic of it, it is the fact that it is based on undeveloped and blind emotion. You don't stand a chance arguing logic because that is where liberals outshine conservatives. They are better able to see facts, you are better at detecting underlying emotional irrationality that triggers their contempt. They will see you as logically inept but never their own lack of the moral character that that allows you to empathize with those they hatefully condemn.
