Most people have bias because they lack perspective or are stupid, or both.
That, or they want money. For the most part, these professional people are not professional. They were young, they said "I want to make a lot of money", and then they worked hard to get their degree. Now that they have a job they can do whatever they want and still get paid, and naturally they will take the path of least resistance.
Great are the people who naturally have you in their mind. The psychologists that are 17 years old who will talk you out of killing yourself or make you feel so loved and important despite still being in high school. They are just smart. They understand what you are saying here; if everyone was nice, then the world would be better. But the asshole individuals won't take on that stance because nobody else will. Then they are working twice as hard to be nice to everyone but nobody is being nice back. It's a circular shithole that humanity won't get itself out of.
I think a huge part of the bias-free objective caring viewpoint is whether an individual has done psychedelics before. I see that theory proved correct to me time and time again. After a person lives a life as a speck of dust while tripping on LSD or mushrooms, they can see what it is like for other people. They act as if they were actually a logical judge for what makes people feel good watching the environment they are in from a third person perspective and thinking "Hmm, everyone in this situation would benefit if this person did this." Then they act the way they imagine the best way to be.
The only thing you can do is realize that you and others like us are better than the people you speak of. When they act like fools, imaging them a 10 year old child going "stupid! idiot! dummy! you smell!" No matter how insulting the kid can be, you know they are dumb and inferior in all ways, and you simply laugh off their remarks as if nothing was said. Because nothing was actually said. When nothing says something, that something has a value of nothing.
