The same reason killing someone in a video game isn’t murder.

But to keep it in the realm of sexual fetishes: It’s why liking furry isn’t beastiality Or why the insane amount of step-bro porn isn’t incest Or why rape porn isn’t, well, actual rape. Or why liking guro doesn’t make you a serial killer.

And so on with any other “problematic” fetish.

It’s all fantasy and has no baring on anything in reality. It’s a huge waste of time to try to get people in trouble for thought crimes that they won’t bring into reality.

Sure you may think it’s weird. And that’s okay. Any fetish is weird if you aren’t personally into it. Especially the problematic ones. But at the end of the day, They aren’t hurting anyone so what is the problem?
