Sarchasm - the gap of understanding between the person being sarcastic and the person who thinks they are serious.
Caste and reincarnation has long been used as an excuse for brutality and oppression of people and women. They supposedly deserve brutal treatment, it is their karma to suffer.
Since we were already meaning caste cultures and women would be a part of a caste already, I assumed your comment was about something in non-caste America.
