Huh? Maybe at Harvard, but MIT has a sizable conservative Christian population. The pro-life group and evangelical Christian groups are very active. The students in Christian groups are just generaly quiet about their conservatism because nobody wants the trouble that comes with saying you are against gay marriage etc. and have better things to do. For one thing, I was a year ago one of them before I moved out of that forsaken state after I graduated. I haven't met a Christian conservative at MIT that is gay and I know most of them.
