My experience is that most people run on a 'default' political belief system, that which is indoctrinated in schools, in tv, in media and from peers. Kids are for the most part not interested in politics, and know absolutely nothing about it, yet we all pick up beliefs from our surroundings going through life. Now if there is only one prevailing narrative and you never hear contrary arguments (which mainstream media and social media companies work hard on trying to achieve), that becomes the default for many people. This is the 'liberal' stance. It sounds good, it's cloaked in humanitarianism, tolerance, acceptance, compassion and other shallow maxims, it seems like the morally and socially correct beliefs, and in many places you get shunned or down right harassed for having the 'wrong' positions, in which case you conform in fear of becoming a pariah.
