Not everyone who is neurodivergent has a neurogender, only those who feel their gender is influenced by their status as neurodivergent. Neurogenders are exclusive to those of a given neurotype, though oftentimes there are similar terms available to neurotypical people who have similar experiences and don't wish to appropriate.
Flag
The neurogender flag was posted on the Tumblr blog Pridearchive on August 13, 2014[1]. The color meanings are as follows: Red, green, blue and purple represent the spectrum of different neurotypes and gender identities that neurodivergent individuals have. Black represents the aromantic and asexual spectrums. The infinity symbol represents neurodiversity.
