Question about urinals

Why are boys and men expected to expose themselves to other boys and men in the restroom?

If this is how males are conditioned to think of male bodies, I don't think it helps them to be respectful of female bodies.

Might it also be less expensive, less contentious and less time-consuming to eliminate urinals than to remain mired in controversy over how best to serve the needs of the transgender population?

Personally, I think that too many people are changing gender.  I'm concerned that the various emotional and physical discomforts of being human are being confused in the minds of younger people with having been born in the wrong bodies.  I also think that the gender stereotyping which continues to confine people of all ages is detrimental to everyone.  People shouldn't be made to assume that their interests and inclinations all fall into gender categories.  To my mind, that's what the feminist movement was for: to stop those assumptions, not to set one gender over another or to glamorize perpetual conflict.

It doesn't surprise me that the traditionally male-dominated medical profession hasn't raised more of a fuss, since changing gender costs money and confronting gender roles is free.
