I’ve heard reasons for it like "women’s bathroom needs places to dispose of pads/tampons but, like, it’s a box on the wall. Put one in both.
Also heard reasons along the lines of “men are faster at using the bathroom so why should we need to share with women” (even though with single bathrooms the washing your hands part is the time bottleneck, not the peeing part) or just general disgust at the idea of sharing a bathroom with the other gender (have heard it from both genders).
