Obviously there’s a lot to unpack here and it sounds like your issues go deeper than what internet discussions can fix, but I would recommend the following:

• stop making assumptions about people. Everything you’ve said suggests that you are making judgments about people’s entire world view and personality based on fleeting interactions. You don’t know shit about them.

• people are nuanced and contain multitudes of thoughts, opinions, behaviours, emotions, etc. their outward expression on any given day is dependent on a bunch of stuff like hunger, tiredness, stress level, etc.

• take a dialectical view. The whole point of leftist theory is that things, including people, can and do change. Implicit in your hatred is the assumption that negative things you observe are the natural or sole state of someone, which is contrary to leftist thought.

• actually make connections with people. Empathise with them. Think about why they are saying what they say. Think about how you would respond if you had the experiences that made up their life. And if the answer is “my life was similar but I made it out”, try to turn that into empathy and not condescension. Not everyone is as capable of throwing off the shackles they were born with by themselves.
