There are SO many different perspectives in the world that I think the only universal truth is that there is no universal truth. There are people on the other side of the world who still think that you must kill for religion; that fair skin is supreme; that homosexuality is a sin; that women exist merely to serve men. It sounds horrifying to us, we think they have been brainwashed and pity them for their primitive mentality. But is it not mutual? They must have equally valid justification for their beliefs.
Then who’s to say who’s right? If there’s no validator, there’s no right either.
