Just because one of the sexes is treated differently in some way doesn't make something necessarily sexism.
It's just that female nipples are considered sensual while men nipples aren't. That's because female nipples are indeed sensual (and play a special role in reproduction and human sexual selection) whereas male nipples not so much.
(Sure, some men like to have their nipples rubbed, kissed, etc, and some women enjoy them. But you can find some percentage of people who enjoy anything, including sexually aroused by armpits, so that's not really an argument. Statistically, males enjoy female breasts/nipples sexually far more than women enjoy male breasts/nipples, hence they were considered more sexually explicit).
In the end, though, is it arbitrary? Yes, but so is considering dicks and testicles and pussies "bad" and sensual, and I don't see many people complaining they can't show their dick/pussy on Facebook (whereas, they should probably complain about that too).
Rationally speaking, without the baggage of culture, there's nothing special about dicks and pussies other hands and faces and toes.
Within the baggage of culture, however, they're in a different class, a class that female nipples happen to be also considered to belong to but male nipples not. But it's not like both men and women don't have several body parts considered censor-worthy. Woman having one more is not based on sexism (if that was the case, only women would have "shameful" body parts to hide and men would be able to display their dicks and balls and asses around), it's based on what culture considers sensual.
That is a pretty good definition of puritanism..
But it is Facebook catering to the puritanism of the parents for marketing purposes.
More like even better. Glad to see a website exercising critical thinking.
> Are a transgender person's nipples allowed, or not?
Is it sexually suggestive? Then no.
> A gender-neutral standard would be better.
Well that's a policy ignorant of reality.
So "critical thinking" to you means rejecting the notion of gender being anything but binary and static, despite scientific evidence to the contrary? Interesting definition you've got there.
> Is it sexually suggestive?
Nope, no subjective opinions or controversial judgment calls there.
> that's a policy ignorant of reality.
It's a policy that doesn't allow neanderthals to deny others' reality, and IMO the fact that it makes those neanderthals uncomfortable is a bonus.
EDIT: I hope people reading my post understand the difference between explaining vs. endorsing another party's reasoning.
That said, I think it's silly. They're a technology company that should be able to come up with a technical solution. Twitter handles nudity just fine.
Similarly they seem to allow people to post comments like "why don't you use your guns to kill yourself" and "I hope you f*cking die" which are actual comments I've had when commenting on posts where the second amendment is being attacked, report them, and get facebook telling me an hour or days later that they did not violate community standards. I even had some in my messenger inbox before and got the blah blah blah it's ok, you can block them if you want message.
You realize that if the post is removed, that "seeing what will happen" has a real consequence for the poster, right? If feel like that's even worse than reporting it because you actually believe it's objectionable.
One I reported was a woman doing duck lips, in a few second video lip, with one breast completely bare and the other mostly exposed with her child appearing to be wholly disinterested in feeding while she actively squeezed her breasts together with her inner upper arms and rotated back and forth to showcase them. Reported it, thousands of likes and even more comments, did not violate community standards and allowed to remain. Literally came up, shared by someone, while I was sitting at church waiting for a meeting to start. It was blatantly obvious she was just finding a way to show her breasts off, I feel no remorse for reporting her post, especially when her blatantly showing her breasts off ended up being 'fine' to Facebook.
