Gary,  lunch sounds great...but...this  dialogue will only succeed if we have some true NCU/Hobby Lobby Christians as guests too-- so far this list looks like a bunch of fellow infidels.
But it's not impossible- you may remember the violence surrounding Measure 9, the  fundamentalist anti-gay measure on the ballot in 1992. It was ugly.   In fact, Springfield conservative Ralf Walters and local gay rights activist Scott Siebert wound up shouting  at each other on the  old  Phil Donahue TV talk  show.
Well, Jack Roberts (yes, that Jack Roberts,  one of the the last remaining liberal Republicans) and I organized a press conference with  Walters defending the bill, and Siebert opposing it.
It worked remarkably well, with the two ending up hugging each other and declaring that while they  strongly opposed each other's positions they could embrace one another as friends.  
The only unhappy  person was the TV news  guy who was disappointed there was no screaming and shouting to film.
