nsfw doesn’t mean “sexual” it means “not safe for work” meaning “It can get you in trouble if it comes up on your screen at work”.
this applies to myriads of other public social situations as well. In a dorm commons, at a coffee shop, places where you’re in public when you want to avoid people seeing you looking at social situations.
so stop trying to make a political statement by not listing nudity as nsfw, which it is, and actually be considerate for people who don’t want to get fucking fired because their boss sees them scrolling past nude images on their screen while on a break. and so on with every other situation you could be checking social media sites in.
