Then oddly enough, it becomes less about you being challenged and more about those who believe you shouldn't exist being challenged. Colleges are great for exposure to peers with varying backgrounds and beliefs and are great for fostering understanding of each other's viewpoints. Isolating your group to spaces of the same people will probably strengthen that demarcation and lessen the incentive (and the ability) for those with hardened beliefs to understand the other side's viewpoints. Sometimes all it takes is befriending one LGBTQ to melt that belief.
