Everyone likes (and dislikes) by what one can understand, by the stereotypes in one's brain. The fake sense of self (the ego) creates those stereotypes, at its base it has the purpose to help us function, to remember, to learn and not make the same mistake twice. But when we finally end up acting up to those preset thoughts in our every move, without the light of consciousness, without constantly questioning and reasoning those thoughts (to recondition ourselves and align again with our non-judgmental, ever-loving Being, like when we are born), then we lose ourselves in a world of judgements, sides to be part of and ennemies (good or bad, pretty or ugly...). And that is detrimental (negative) for each and everybody. Be aware.

(That's also why, i think, after some years living on this planet amongst others, our corrupted mind is seemingly naturally attracted to mediocrity)
