That was one of the arguments for gay marriage, when it was a tiny, tiny, tiny, tiny percentage of people who experienced that, and was basically meaningless. It was an emotion ploy to get their way and push the agenda that had been decided upon.

To go into the specifics, it was basically when one member of a homosexual couple had some health issue (and generally needed to be in a coma or otherwise unresponsive, I'd assume), and couldn't make their own decision, and their partner didn't have permission to make those decisions, so it fell to their "hateful, homophobic family" instead. I'm sure it happened, but it doesn't even make sense to act like it was happening on the large scale, but that was the mainstream argument, and no one really questioned it. As I said, it was a statistically insignificant thing that was used as an emotional wedge issue.

Similar to how statistically almost no abortions are due to rape or incest.
