I have a categorically negative attitude. I don't understand why you should disfigure your body. If I meet a man/woman with a piercing on his/her face, then a priori I will have a negative attitude towards him/her.
I think they serve a useful function... as early warning signs. Any person who has piercings isn't likely to be one I'd like to interact with, so I appreciate the heads-up. The only acceptable option is to have your ears pierced if you want to wear earrings (if that even counts as a 'piercing'), but even then that can range from tasteful to tacky to straight up deranged.
Personally not a fan, but similar with tattoos a small amount I can overlook. Small/Medium amount of ear piercings I think are my limit honestly, every other piercing location/amount is not it for me-
