"Don't yuck another's yum" is great #kink advice to follow.

It's 100% ok to not share or enjoy a kink, or even find it upsetting (trust me. Plenty of people find their OWN kinks upsetting).

But keep it to yourself, don't reply to people enjoying a kink to say you dislike it.

I try to only interact positively with kink stuff. No response is the right response if you don't like something. No need to inform people you don't like it. (we always know it's niche)
