Modern Liberalism: CLS = KKK?

At least for officers, the Christian Legal Society student chapter manual prohibits "homosexual conduct" (along with fornication and adultery).  As such, I'm not at all confident in liberalism's ability to distinguish between the CLS and the KKK.  Let's assume that the student version of the KKK condemns violence and even allows racial minorities into its ranks provided that they swear allegiance to the principle of white supremacy.  On what basis would the modern university spend funds supporting one group but not the other?  (A response grounded in the distinction between the person and the conduct seems a non-starter in the wake of Lawrence.)

My inclination, for what it's worth, is to let both groups in and allow the marketplace of ideas to flourish.  (My answer would certainly be different for an elementary school.)  Under a marketplace approach, the university should be entitled to withhold student tuition funds from groups it opposes and promote groups it embraces, but it should not deny disfavored groups meeting space or official recognition, both of which are essential to the groups' campus viability.
