Who are we to judge?

We all judge people, but who are we to judge, when we're just as bad as those we judge? Why do we have all these prejudices against each other, people we know, people we don't know. Some of the prejudices is based on rumors, and why, why do rumors start? And how, for the matter? And why are we so judgmental? Just because we're not all the same, we're all different, we can't all be alike, can we? And if we could, then, wouldn't we be shallow, in the end? We judge, and people judge us. But is that just a matter of life? For all of time, I believe that people, have judged and been judged. And maybe, we judge because, we take a quick conclusion, about one individual we don't know. Maybe, we want to feel less threatened, I don't know. Okay, there's a differences on judging and talking bad about another individual. But doesn't they kind of, walk side by side, doesn't they look a bit like the same? We talk bad about other individuals, because we judge them. So judging and talking about others, is that just the way we are? And can it really be, that we are so horrible, us human beings? I hate to talk bad about others, but still we do it? We judge, we talk, we listen to rumors, we let all this get the best of us.
Can it be, that we are just shallow, judgmental homo sapiens?
