Human nature is not a defined value. Nor will it ever be. Rather you should use Structuralism/Agency theories to help define aspects of human nature.
Marx and Engels - Capitalism, Alienation, Class.>Bourdieu - field and habitus, social-cultural-economic-symbolic-capital>Max Weber - class, social mobility.>Gramsci - hegemony>Connell - hegemonic masculinity>Foucault- power, surveillance >Parsons - social action>Goffman - impression management>Beck - risk society
Realistically you only need Marx and Engels, the other subtheories are just that.
To believe in anything other than Marxist theory and other subsets of the theories from the left is just retardism. ie Trickle down, Neocon, Egalitarianism, Social Darwinism, all laughable pseudoscience and brainlet ideologies. dont argue, scoff at the able-minded subversion of knowledge.
Just remember when you represent the cause on the internet, people will see. Don't sperg out, know when to cut your losses. show mercy to the feeble and cunning ruthlessness towards the enemies. If you do not have an army you must be an assassin. cut them down with one strike. Be a leader and others will follow.
