Weird, how all the people who like to tell us that males in women's spaces are no problem suddenly find that two female eight year olds consenting to shower together is enough of a problem that it needs to be called an "incident".
What if one of the girls was trans, i.e. had a penis? Would it then be totes harmless because all males are totally harmless little angels?
The hypocrisy of it all is so annoying.
They're 8, at that age where some start to explore their bodies. They should definitely tell you. Because things can escalate really, really fast & am sure you'd have hated yourself if your dd mentioned out of the blue that so and so (boy, girl, or intersex) touched her down there when they showered.
So because you cannot keep up the lie that males do not sexually molest girls, now the lie is spun that eight year old girls are as likely to molest as males of any age? So that you need not face the unpleasant reality that males are much, much, much more likely to sexually molest girls?
Get a grip.
I really don't see why eight year old girls should be shamed about perfectly innocent behaviour just so that adults can lie to themselves and don't have to deal with uncomfortable facts.
Your "things escalate really fast" narrative suits the need to minimize male sexual assault by implying that "things escalate" instead of, you know, males deciding to assault.
Furthermore, in this "incident" there was a choice involved. Two girls decided to shower together. Because they trusted each other. But girls and women getting to choose whom to trust is also something that is out of fashion these days.
Because they might choose to not trust males. And then you would, again, have to think about uncomfortable facts.
