Minnery and his ilk use the "clobber" verses from the OT frequently to try and justify their hateful actions. Sorry, but you can't have it both ways. You either follow Jesus or you live according to the OT law. 
And yes, I am well-versed in theology. At the root of Christianity is Jesus. The great I Am. Christians are supposed to be those who follow Him. And Jesus didn't say a thing about homosexuality.
