I know many retards (forgive the word) who will sacrifice themselves for you if you ask them, without getting anything out of it. People are just too damn greedy. I just really dislike it when they mask it as doing something miraculously right, when they're only being selfish. Don't do something egoistically and say you're being altruistic, that's what I say.

And also, having things half-half means there are no minorities, and in such case less ignorance and prejudice/etc. We are already 7 billion, as you said, it's not like we need to reproduce lol
