Why do they say be human when they mean warm, kind and friendly,

... even though humans are horrible creatures?

We (not all, just a provocative generalisation) exterminate other animals, we destroy habitats and are responsible for the deterioration of the climate. We kill each other out of revenge or greed and retaliation (or in war because someone told us to). We betray, lie and exploit each other and. There are so many things that we just seem to fuck up on purpose.

Of course there are people who help other people, but are they really more people than those who harm the earth and its inhabitants?

I am not saying that all people are equally shit, but you will know that each of you has some good and bad qualities. However, humans are generally not the nicest creatures on this planet. I sometimes think that we are only nice because we were brought up that way. Otherwise we would all be selfish, self-centred, greedy, stingy and much more. Probably the upbringing evolved because such a person wanted other people to be exploitable, learning early on that they had to discard that behaviour in order to be accepted. But that's just a thought.

Why do we say that one should be human? When I look around in the world, well-known people in particular are quite often inhuman by definition. At least that's the case in my place.
