Close-Minded Christians?

We hear it all the time from the Left: Christians, particularly conservative Christians, are close-minded and intolerant. How does this perception jibe with this data regarding the conservative Christian students of Vanguard University, an Assemblies of God liberal arts college in Costa Mesa, California? It certainly appears to counter the Liberal perspective with facts (not the first time that's happened!):

Diversity
-33% of Vanguard students took a Women’s Studies course (vs. 16% for religious colleges, 22% for national sample).
-42% had a roommate of different race/ethnicity (vs. 33% of national sample).
-68% socialized with someone of different ethnicity (vs. 49% of national sample).
