Liberals are collectivists who relinquish individual thought to higher points of authority. Liberals don't question whether or not they are morally right because they prioritize authority over individual thought. If the news, a president, or a 'trusted expert' makes a statement, that statement is trusted blindly and assumed to be true on all counts. Should someone in a high point of authority make a statement that contradicts an older statement, the new statement takes precedence and overrides the authority of the previous statement. Since liberals do not process information through their own personal lens, and authority is what bolsters credibility, the liberal feels he is always correct. Even if two seconds ago he believed something totally different. If the media suddenly switched to loving Trump, I guarantee that the vast majority of liberals would follow suit and begin to like Trump. Don't believe me? Look at Elon Musk. I am not saying the guy is perfect by any means, but his influence is undisputed on bringing about revolutions on multiple fronts: online digital payments, electric vehicle production, charging infrastructure, grid battery backups, discreet solar roofing, rocket technology, global internet infrastructure with Starlink, Starship for future Mars colonies, hyperloop for rapid and efficient transportation over vast distances, Neurolink, making the blind see and the lame walk. Yet now all the liberals hate him? Ask them why? They really don't know. Liberals will often vehemently defend 'their stance' on something, but if you ask them to elaborate, often times, they are quite stunned that they literally have no reason at all nor any evidence to believe what they believe. Blindly following authority does not automatically make someone a bad person, however. It depends on who they are following. That is why it is vitally important to ensure positions of power are occupied by morally grounded people of strong character. Many liberals do not have an internal monologue, or even remember WHY they did certain things in their past, only that they did them. These are facts, and this should elucidate why you cannot argue with a liberal. Liberals are not a few facts short of being conservative. You cannot argue with them because their arguments are not based on fact, but rather societal authority. A liberal always feels he has the higher ground because he is cloning the positions of high authority, which are ultimately assumed to be morally infallible.
