Ah. So wholly sex based thinking and essentially the feelings, voices, preferences, privacy and dignity of female people (not women, only female people) should always be subordinate to the wishes and choices of male people.
That's plain old boring incel male supremacism isn't it?
If Penny's happy to get her kit off in front of any male person then good for Penny, I'll hold her coat. But unless we're saying that female people do what male people want or are excluded from society - which would obviously be absolute shit equality, inclusion, intersectionality and even basically moral - then spaces for female people must be provided alongside the mixed sex spaces, and male people must respect that they cannot use that one lone, female-needed option and must settle for using and choosing from all the other ones available to them.
