Okay...
Women ****, fart and even go full simian and finger paint with poop in public restrooms (I recall several bathrooms being closed for such reasons growing up stuck as a female). I've seen blood smears, blowouts, crack-shaped poo stains, piss on the floor and used feminine products tossed openly on the floor.
Now, is every women's bathroom a war zone? No. But exercise basic tact and you'll already be ahead of a decent percentage of cis women.
Also, I pissed weird for a cis female; it's great now, but it sucked before. I used to absolutely loathe using female restrooms because, in order to sit down and piss effectively, I'd have to almost bend in half or I'd piss a solid stream right out onto the floor. As a result, I'd end up just hitting the side of the toilet bowl which would dampen the sound like someone with a penis. In 27 years, no one ever commented or noticed.
Now, I happily stand and freely piss jet streams. Life is much simpler.
Anyway, 99% of the time, we're the ones blowing the tiny little things out of proportion in panic.
