Speaking as someone who has had plastic surgery I can say now that its a definitely big fat yes I would date someone who had had plastic surgery.
When I was a kid I had appendicidix and peretonitis. This is basically me having an appendix be infected, burst, then infect everything from the stomach down to the ovaries. I couldn't talk at the time so I couldn't tell my parents it hurt like hell and my stupid GP had no idea what was going on so it happened.
When mum finally decided to screw our GP and take me to the hospital they did exploratory surgery and found my infected insides. In their rush I didn't get a pleasant keyhole surgery they opened me up completely and jammed my body full of antibiotics. As well as that I had an allergic reaction to the antibiotics they were jamming inside of me which made things worse.
When they sewed me up there was a huge jaggered scar when the skin was attached to the muscle underneath leaving a jaggered ditch looking scar.
Now sure, I could have left it that way, I could have been 'meh its a scar' but you guys have no idea what its like to have people look then look again in horror. Constantly ask questions about it, non stop. It was a real sore point and sure I tried to laugh it off but it just wasn't that easy.
So when my mum asked me half a year ago if I'd like to fix it, I said yes all the way. I still have a scar now, and its still a lot longer then the scars other people have, but it doesn't look like a ditch and in about a year it will be white and blessedly you won't be able to see it from a distance.
Now its really really really god damn easy for someone to say
'people judge you from the insides' but as having a problem like this before I can say that is sooo wrong. Sure people will treat you nicely AFTER they get to know you, but unfortunately I like to meet new people and I like a nice impression on them like oh she's nice. not OMG SHE HAS A SCAR.
To me having boob implants usually only happens to people who have AA size cups, or have a breast reduction due to back pain. Sure they'd survive life, but there are less difficulties and more self respect if they have the surgery done.
I really really don't think someone should judge someone else for certain procedures they may have had done until they learn the reasons behind the surgery. Especially when plastic surgery is a whole lot bigger then cosmetic surgery.
