I went to college as well, and in a bastion of liberal beliefs, introspective thought as to what you believe and why, your hopes and dreams for your future, and learning about other people's experiences.
The truth is that everyone just assumes that there are no differing opinions, because how could anyone NOT be a Democrat? I saw a lot of circle-jerks and very little discussion. These kids don't want to hear different opinions or open their minds. They want their "safe space" where they can bash on those uneducated, hateful Republicans.
It got to the point where I wouldn't open my mouth because these people are extremely emotional about their beliefs.
