> Dismissing a multi-millenia multi-cultural fundamental norm as "indoctrination" severely downplays the collective learning of uncountable generations.

I agree in this case, but only because I think marriage is an institution that we’ve learned needs (sometimes strong) active endorsement and it’s pro-social.

My view is that cultural norms are at worst tyrannical and at best the essence of being human.

> Social iconoclasts dismiss organized religion, marriage, sexual norms, social duty, gender roles, and cultural traditions.

This is just true. But this is all of us: we all have a relationship with society around us and dismiss parts of it. As we should.
