People are social animals. Our opinions on norms (homosexuality, cannabis, murder, monogamy..) are are generated socially. Individuals forming their own opinions, sharing them, dissenting and such is what social norms are made from... Individuals are drawing from the herd brain and contributing to it. No one's opinions are their own. If you grew up in a different time and place, your opinions would be different.
