is the pollock stereotype actually true

hey, i'm going to edinburgh in september and my accomodation is baird house in pollock. i've recently become aware of the stereotype of everyone being privately educated tories, and, according to a second year i spoke to, 'very heterosexual' (not a problem in itself but it'd be nice to meet some fellow non-straights). i'm a state educated lesbian and most definitely not a tory, and now i'm kind of dreading it. are the stereotypes actually true or are people just exaggerating?
