Short answer? I don't.
What if your worldview just happens to align neatly with your temperament, your social environment, or whatever gives you emotional relief?
It does. The things is, though - I happen to prominently share basic human values, such as kindness, mutual aid, cooperation, and care, all of which are normally seen as "good".
My social environment is very median, and I do understand the regular person as I am one. I know the struggles people in my group face, and am open-minded about struggles of others outside it.
I feel relieved in the world where people are good to each other, and if that's not what we strive for, then humanity has abandoned the very core of its own morals. When such basic things are betrayed, it's always a sign of corruption, an attempt to justify greed, or selfishness, or something else.
Then comes the critical examination of ideas that claim to lead us there, whether they could be contradictory and leave us with a very different place than we intended, either because not enough thinking went into original concept, or because it was a con to begin with, clearly serving the corrupt interest of the few.
