You are the second poster on this thread to use that phrase. Unfortunately, the homosexuals are not a group of "live and let live" people. They insist that not only must we recognize their relationships, we must approve. Not only approve; but, celebrate who they are and what they do.
If they were willing to "live and let live"; then, the baker who refused to bake a cake celebrating "gay marriage", and who offered names of other bakers who would be willing to bake the cake; that baker would not be involved in a lawsuit at this moment. Tolerance is a one-way street for these bullies.
The banal evil of same sex marriage is when a single mother gives up a baby for adoption to a two parent family so the kid has a mother and father and it goes to one with two mothers.
