left/right dyad is more intrinsic than political debate. it has to do with conformation to the social group, and reliance on the social group for confirmation of internal ideas. a person either trusts themself or their social group more. if they lose confidence in themself, the social group can take over executive functions, causing the person to become a leftist. if you rebuild trust in the self, or if the social group experiences a significant setback (woke goes broke and dei dies), the underlying confidence calculus recalculates, and lefties can become righties (or vice versa).  you are in a social setting with your friend. for you, you do not rely on your friend for opinion formation. your friend however is not like you, your friend does rely on you and others for opinion formation. the opinion you were sharing is not compatible with the other people in your friend's social group. therefore your opinion has put your friend into an 'us or them' position and you lost, most likely because of 'one' vs 'many', qualitative vs quantitative analysis. tldr lefties are all about group compatibility, and if your ideas jeopardize in any way their social access, you and your ideas are out the door. the despair and desperation of loneliness and isolation are too powerful motivators, the lefty 'stick' compels better than the righty 'carrot' of not caring more about politics than friendships.
