Welcome to college. This is true of nearly every college including the very elite.
Go ask the same question on the Rice or Chicago forums and see what they say.
Also, these niches you speak of are much larger than the high school counterparts. And in Emory's case, the diversity will help you a lot.
Many colleges (especially private colleges) are what many consider bubbles and are to various extents insulated from such things. Emory can be considered very insulated from the perceived culture of "old money" in the Druid Hills community or most places that would even be considered southern for that matter.
While Rice and UChicago students may give more sophisticated answers, it is foolish to believe that those at either party less because of that.
I can't speak for Emory, but I suspect that's one of the benefits of any sizeable school -- something and someone for everyone.
