If it’s old women, people object that the elderly are being disrespected. If it’s young women, proper object that they are only young enough to die in a war but not old enough to decide if nudity is appropriate for themselves.
Or we resort to saying somehow women are inherently always disadvantaged in any nudity related real. Male actors though can handle themselves... somehow.
Which in the end is just a restatement of “sex = icky” but with more syllables and hotter tempers.
