Your point here is so profound because if this is a non-binary person, then their breasts (or chest, post-top surgery) are neither male nor female. So with or without the top surgery, there is nothing gendered about their nipples. (Which is medically true, regardless of their gender identification.)

I wonder what Instagram is going to do about THAT.

P.S. Send me a link to their account, please, if you get the chance! xoxo
