@ehBeth,
I would guess that there are divorce lawyers that are seeing dollar signs.
In other words, fast forward twenty years and a sociology course might include the percent of marriages that end in divorce for heterosexuals, and the percent of marriages that end in divorce for LGBTs.
I wonder if there will be a correlation for marriages that stay together when there are children involved?
When all the partying is over, and all the self-congratulatory news items are history, the real benefactors might just be the children that previously had no real parents. What would that say about an LGBT couple that chose never to raise a child? No difference from the heterosexual couple that "chose" not to raise a child I would guess?
