Why are people so mean?

I’m trying to trust again and assume people are not actually lying.
But yet if I speak up or reach for clarification, people snap and laugh and say the world sucks and people are mean etc etc.
•Why do we all want to trust but we all refuse to show others they should trust?
It’s a constant silent war with zero end in sight.
•Is division between people inevitable?
•Are we not supposed to be social?
•At what point do I believe people if they are so proud to be so mean?
Why are people so mean?
