What’s the potential “fallout” over this?
All the theories are unsupported.
It's "nippleism" and politically incorrect because it is offensive to women who have suffered breast cancer and mastectomies.
(I'm only half joking because I hate political correctness in all of its fascistic forms, but at the same time, having lost the love of my life to breast cancer two years ago, I know first hand how emotionally painful it is for a woman to lose them.)
