Why can women get away with doing things that would have a man locked up?

I just unfriended a FB acquaintance. We’ve known each other for about 8 years. We worked in similar capacities so our paths crossed often. I don’t know her outside of that.

She constantly posts naked pictures of her son. I guess he doesn’t like to keep his clothes on, and that’s fine. I had a kid and a couple of grandkids like that. When her son was 2 it was kind of cute, but he’s closer to 7 now and it is NOT cute. You can’t “see anything,” but it’s still weird. I can’t help but think that if a father was constantly posting naked pictures of his daughter, even if you couldn’t “see anything,” he’d wind up in jail.

Why would there be all kinds of red flags raised if a dad did that, but not when a mom does it?
