Between Barnard, Columbia College, SEAS, and GS, there are roughly 11,000 undergrads. Many different people, many different types of people, many different interests. The campuses are closely integrated, both socially and academically - so there really is no way to characterize a “relationship” between the students as if each school was a homogeneous lump. Certainly the supposed attitude of Columbia students toward Barnard students was never a factor or concern for my daughter.
