I think the majority of CMU students are very welcoming, or become very welcoming after attending CMU. There isnt many racial, religious, socio-economic, sexual orientation, etc. issues. There are some ignorant individuals but they in no way reflect the majority of the CMU student body. I honestly can say that I don't think there would be a single student who would feel out of place at CMU. To back this claim up, just look at the wide variety of majors available at CMU and how the majority of them are highly ranked. I see so many different type of people that im sure ANYONE could find a group of friends just like them if not, CMU allows the opportunity for people to step out of their usually type of friends and make new friends with people of all varieties. I can say that I have never seen a single person wear their PJs to class, but I'm pretty sure it happens. People wear all different types of clothes, so people dress up everyday, while others wardrobes consist of nothing but sweats. That is the best part of CMU, the fact that soooo many different type of people are able to interact. I have friends from all over the US some from Korea, Singapore, India, Cuba, Turkey, etc. The tables in Schatz (the ONLY dining hall we have): Table 1: Football players Table 2: Drama students Table 3: Freshmen guys from Hammerschlag Table 4: A group of friends catching up on new info in their lives that they've missed b/c they had a huge exam that week. Most students are from Maryland, New Jersey, India and Korea. You never really know peoples financial backgrounds b/c in college everyone is poor:)...however, I can guess that the majority come from wealthy families b/c all the international students get miniscule to no financial aid and their parents pay from pocket. I think most students are liberal, CMU has many LGBT individuals and its likely that you'll have at least one friend who is so I feel most people are liberal. However, Im pretty sure we have a Republican Party club, but not a democratic one. I'd say some students are politically aware but not active, there's just not enough time for that. People talk about that alll the time (i can only speak for engineers)...that is the reason why some students chose CMU b/c with a degree from CMU you're almost guaranteed to be successfully (financially)...I can assume the same for the business majors as well.
