Diversity matters and as an Irish Catholic I've benefited myself from being accepted in places my parents weren't allowed because they lacked the proper birthright.
Unfortunately, or fortunately, some have been born at a time when they think nobody has negative generalizations about them based in their background, looks, body type, etc. Sad but true, we still value people on how they look.
Back to subject socializing (getting laid included) is also an important reason to go to college and a fast way to become independent from parents, family, etc.
