I hate when people romanticize abuse and claim that they want it, so I just say "okay, have fun"
When people romanticize abuse do you want to show them what abuse looks like?
No, they don't know what they really want and I want to save them from themselves.
While people can have their own kinks, it's wrong to want to be abused since it is both emotionally damaging and physically dangerous. Only among consenting adults should such rough BDSM behavior be permitted and only under strict rules of what is allowed and isn't. Without consent, that kink turns into actual abuse and it is something very wrong and immoral to do.
It's fine, people don't know what they are doing when they are too inexperienced.
Well it sounds like you really try to be understanding with them. I hope you're able to make some of them realize that they are wishing for the wrong thing.
