Human Nature?

That age old argument that Communism is against “Human Nature”. Love it, but it makes me so mad, everyone jumps to it, because that’s what everyone was taught in school. If I tell someone in my grade I’m a communist and they say ‘no, communism would never work because it’s against human nature’ I know exactly who told you that. It’s not your thought, it’s the status quo’s thoughts. 
Think for yourself. I’m not telling you to become a communism I’m simply asking: where you born with a predetermined thought of what “human nature” is? Or was it “nurture”?
Because it’s not against MY human nature.
