Teen Pregnancy in upper scale schools vs lower scale schools?

today if your 16 or even 14 and you get pregnant you get treated like a tramp or some type of sl*t by people who don't even know your situation in allot of upper scale schools i have noticed or you get stared at like some type of disease. like for example i have a young friend who is 16 ,in high school and is pregnant. she attends a school that has an outstanding educational system that is very privileged. but there allot of people Single her out and call her and slut amongst other things. not knowing that she is NOT any of those names and has only had one boyfriend who she made the mistake of getting pregnant by. while when i visited a lower scale district that was not by far as privileged as the other school the girls who were pregnant didn't called any of that people where nice and very understanding. why is that? or is it just the mentality of the diffrent areas?
