Like even offering it is becoming a negative thing nowadays

For sure. It has been seen as a belief that someone is incapable, even when they are. It is about ego, not reality.

A healthy community is not one where nobody has needs, but one where needs can be expressed without shame and support can be offered without judgment.

And herein lays one of the major issues, right? We have a system that is built to judge at every level, regardless of relationship. It isn't people we know, but strangers on the internet in other countries, that have never met. Our "vulnerability" is put to people we shouldn't trust while we are foregoing the opportunity to build relationships with people we should.

So psychologically, we are being trained this way :)

Absolutely. I have another article already written that touches on this ;)
