Are we all aware that they're not kidnapping people off the street and cutting their body parts off? That patients are willingly and knowingly seeking this procedure?
And even kids - these surgeries and injections are happening with the full consent of their parents.
Straight up, I couldn't care less what psychos do to themselves (or their kids). It's none of my business and I certainly wouldn't have wanted them telling me what to do with my kids. (And yes, these nutters think traditional parenting is more dangerous than cutting off winkies and hoohoos.)
I think it's gross, but there's a lot of things that would get criminalized if I were IQotU. Since I'm not, I vote to stay out of people's personal business. And if these folks later regret their decision, oh freaking well. Actions have consequences.
