If you have to refer to a specific gender when you describe something, it’s probably sexist.

Men and women’s sports, men and women’s bathroom, men and women’s clothing, etc.<br><br>In my opinion, anything that specifies gender is sexist, because it singles out gender to be a key component of whatever it is. I’m not saying everything that specifies genders is sexist, just that the specification of gender singles out gender and becomes sexist. I’m also not saying that gender is the only factor being specified, but that it is being specified.
