there are far more important things to focus on. dont bother going around fetish spaces policing what folks can or cant enjoy, you're not going to make any kind of "progress". i implore you to spend your energy on stuff that will actually make a difference... speculating on the possible harm a piece of random fetish content could have doesnt exactly fall in that category.
this is genuinely just fetish stuff, and it isnt for everyone, no, but it doesnt mean its immediately harmful. people have fucked up fetishes. you cant stop that. im a bisexual transgender woman, and sure, yeah, i got some fucked up fetishes, but i wouldnt act on any of it if you paid me a million bucks to do so. this is a healthy way of expressing it, 'n honestly, this is a fairly tame!
