Yes, and no, society has expectations of what it is like to behave like a man and woman. Please, pass your synopsis by women, pay equality etc. Society raises children to conform to gender stereotypes; boys wear blue, girls pink, boys should not play with female dolls etc. Please wear a dress and walk outside. The thread of your argument follows a narrative I frequently encounter, a group raises awareness of an issue that concerns them, gender stereotypes being an example. Some commentators will turn this around and present them as being the problem. Some people are intersex. In the gay community, there are divisions between fems, cis, butch etc. Non-binary to me means not conforming to society's gender stereotypes and expectations.
