and that is very much the point. positioning something worn by very specific groups outside of kink communities for well known reasons as inherently sexual isnt done unintentionally, because this focus on the concept of 'kink' in public is about wanting to control people and justify harassment and violence towards people in certain groups.
when people say they want to beat anyone wearing a diaper in public theyre aware of the fact that includes a lot of disabled people. they already know about collars being worn by trans women to draw the eye away from adams apples, by alternative subcultures, by therians and otherkin, various other people seen as Weird in some way. they know that hatred for them will be more socially acceptable when its framed it as hatred of kink, because its easier to position as bad.
if you say that you dont want children seeing anything done as a kink thing, it sounds like youre Protecting Them. it doesnt sound like you want to say anyone that makes you personally uncomfortable is a threat to children on the basis of that discomfort, it gets turned into some righteous desire for preventing a theoretical harm. it doesnt matter what you obviously mean, it doesnt matter whether that harm exists or not, because youve successfully rebranded your message.
