I have doubts that it will happen, but as a thought exercise what would you recommend to accomplish being less critical of other people?
Faiths that practice detachment, of letting go of one's worldly tethers, seem to find value in trivializing the human experience. I've found it more natural to do the opposite, to delve into it headfirst to the point of people hating my questions, but past a point the questions feel more important than the people.
Much like Jackie Chan's character in Forbidden Kingdom, or Iroh from Avatar, I question how anyone is supposed to let go of the human experience or why there's even value there beyond momentary comfort.
I noticed you like to approach every statement from somebody else as an excuse to contradict and flash your whataboutitis around. To a point where you make some rlly absurd statements that will sometimes contradict what you said last week or last month.
Just stop doing that, smile and nod, read some Dale Carnegie and find excuses to agree with the person and tell them how awesome they are.
Forget all the eastern mysticism. That shit only works for self acceptance. Other people will constantly undermine what you try to do to like them, so approach your goal incrementally. Find a few little things about them that are exceptional, and be sincere about it. Then build on it as much as you can.
