14-year-old girl who was called a "whore" for her pro-Choice sign expresses disappointment in adult world

I think it’s quite indicative of the moral state of the US society that she needs to explain/defend herself by telling everyone about her sexual activity (or lack thereof).

I often get the impression that culture/morals in the US got stuck in the 18th century - heroisation of violence (guns, military, stand your ground, death penalty etc.) and demonisation of sexuality. The US advanced technologically but the morals and culture are those of the founding fathers.
