In a more loving world, the Christian bakers would bake cakes for the gays in order to demonstrate unconditional love, and the gays would avoid going to a Christian baker if they knew it would offend the baker's sensibilities.
(Obligatory position statement: I would bake the cake, no sensibilities offended. And yes I understand that in some states (the deep south, for instance) it would be impossible to avoid offending someone's sensibilities. In a more loving world, everything would all work out.)
