I mean, yes that’s fked up. Not sure how people even get these ideas and decisions. But imagine if it’s just same as when the first person got piercing/tattoo and everyone were freaking out, and in like 100yrs, this sht becomes so normal.
Everything you do to hurt yourself hurts others. You take up our time and our money going to the doctor's to fix whatever shit you broke. You take up your friend's and family's time and money by doing reckless and wildly unnecessary shit. Unless you are literally alone physically, emotionally, and mentally, everything you do affects others, usually negatively.
Also, if she's not hurting anyone then just let the odd woman do her own thing
