While I cannot speak for the majority of your experience, what you just described sounds very much to be related to revulsion towards the inclusion of different biological/reproductive traits within the same, supposedly semi-private, room; this may provoke discomfort within your average female attendants in the room, and works against the design of the rooms themselves. (The rooms utilizing separate urinals optimized for certain sexes.) I understand your reasoning behind have some distaste against this particular viewer, but it is preferable to attempt to understand the philosophical underpinnings and priorities of the other side than merely note said side's existence- such a lack of introspection is part of the problem, not the solution.
