Mark Driscoll and Liberty University

Apparently Mark Driscoll is a commencement speaker for Liberty University (see the discussion here).  Some people are making a big deal about this.  Where were those same people when Liberty University had Mormon Glenn Beck speak at commencement two years ago (link to video and discussion)? Complaining about Driscoll and not Beck is truly straining at gnats and swallowing camels, whatever Driscoll's ministerial or theological shortcomings may be - even if they are numerous (which I doubt).
