#freethenipple is an actual movement that is happening in America, where women want the right to walk around half naked and still be respected and not "slut shamed." I understand where the dress code in school's is too much, for example a 5 year old shouldn't be punished for wearing a spaghetti strap, but completely removing shirts shouldn't be acceptable. So yes. People have a lot less regards for decency.
It's a social construct. There's nothing inherently wrong with your body. Cover your genitia and ass and you're good. I'm mean it's just the human body. You know something everyone has seen. Who cares?
