They will understand that their concept of marriage is cultural, as in the 'wedding industry' that lures couples into spending thousands of dollars they do not have for an evening, whereas those of us who counsel said couples are more interested in five to ten years down the line.
They will understand that their concept of 'biblical' marriage is totally wrong, that this notion of one man/one woman more often than not does not show up as the norm in the bible (try Salomon and his gazillions of wives and concubines or Levite marriage).
They will understand that their concept of the actual rite involves both state and church and perhaps, it would be better to separate church from state in this case, as it is in all other rites.
They will understand that the concept of samegendermarriage is incredibly conservative and traditional and is not going to tear apart their (fragile) heterosexualmarriages.
They will understand that the sex lives of gays and lesbians are boring, and not cracked up to what their fantasies think they are, that the gays and lesbians are not out there 'doing it' all the time but actually are quite bogged down in the mundane tasks and responsibilities of daily life.
End rant.
In the meantime, the arc toward justice is incredibly long and slow.
