Do you think in general Greek Life in college campuses are liberal or conservative?

it all depends on the type of college you're attending and the missions of the greek organizations at your school. For example I went to school at a school in California (SF bay area) and there were multicultural interest sororities, christian fraternities, and business and community service frats/sororities. However the institution you're accustomed to may just attract and focus on different crowds, in your case conservative christian organizations. It varies and the cirstances cannot be generalized very well.
