Yes, exposing your naked self is legally considered assault. I have no idea what you are talking about with the Klan robe scenario unless you are talking about your own fantasies.
The Klan robe bit was showing a very offensive view. We have no legal protection against seeing things that offend us.
No, me seeing penises in random public places or in situations where I expected that there would be penises did not cause me any harm.
Yes, being surprised by a naked body with a penis in a women only space IS the issue.
No it is NOT reasonable to expect women to just assume that the naked stranger next to them in the shower is a trans woman and no threat to them.
No it is not reasonable to expect women to be ok with some naked stranger with a penis to see them undressed in a shower or locker room and to make the assumption that it’s only a trans woman and not someone who might be s threat.
You're still only showing that it's wrong because we don't do it.
What kind of obsession do you have with open dressing rooms and showers? Why are private showers and dressing rooms not perfectly reasonable?
I'm fine with private stalls. Where I have a problem is when the whole area is segregated--what is someone trans supposed to do? What is someone with an opposite-sex caregiver supposed to do? (I have experienced the latter. My in-laws ran into the problem repeatedly.)
Again: I certainly am NOT talking about being offended. I do not find anything about the human body offensive, although I do think that some things people might choose to do with their own human body to be offensive (crapping on the dinner table, for example is not just unhygienic but also offensive). Walking about with your genitals exposed (any genitals) is often but not always offensive, depending on the circumstances and sometimes is indicative of acute intoxication or acute mental illness. Not always, of course. Sometimes, walking around with your genitals exposed is perfectly acceptable and even expected. Context matters.
I'm talking about something that YOU do NOT have any experience with and apparently are incapable of having anything resembling empathy with: Women are constantly in some state of surveillance of their surroundings and of their own appearance and behavior, looking out for danger. Most of us can keep that need for surveillance to a minimum in most circumstances but yes, women are more attuned to signs of danger for themselves and for any offspring they might have. It's hardwired into us by nature and society has taught us that we must constantly monitor our surroundings, our dress, our behavior because if we make any kind of mistake, however innocent, we might be attacked and if we are attacked, every single thing about our dress, our behavior, our surroundings will be used against us in a court of law, if it gets that far. Most of the time, it does not get that far, even if it is reported, which most of the time it is not.
This is not a burden that you ever have to consider or bear and it is clearly a burden you do not have any ability to empathize with. You seem to conflate your feelings and your experiences and your beliefs and insecurities with universal and completely rational. You're wrong.
You seem to believe that all women should simply be OK with having to make the instantaneous evaluation of a naked stranger in a dressing room or shower while they, themselves, are naked and correctly coming up with the evaluation that this is obviously a trans woman who is of course no threat to them at all. I suppose in your POV, this would include if the naked individual was showing (however involuntary) signs of sexual arousal. Because of course women know that men never, ever, ever intrude on women when they are expecting privacy and are not fully clothed.* *Sarcasm because of course women know that they can be attacked anywhere at any time, whatever they are wearing or doing and even if there are other people around.
No one can make such judgments immediately and no one should be expected to do so. It is arrogant and callous for men to expect women to immediately accept any individual in their dressing rooms and showers and to know that they are in no danger whatsoever from naked strangers with penises and have no need to feel modest, either.
Thank you for bringing up a situation I had not mentioned when having private stalls would be extremely helpful: when one needs to aid someone who needs help dressing, toileting, showering.
