It was only in 342AD that the Christian church banned same sex marriage, before that it was perfectly normal, and no one took any notice. Same sex unions are noted during the Ming Dynasty, the Almanac of Incantations from Ancient Egypt, Native Americas, and pretty much every culture.

Remember, astronomy and women priests where banned by Christians at one point, yet we do not wish Brian Cox or female members of the clergy to burn in hell!

As it was only banned based on an untrue story, then it was obviously the wrong decision, as for thousands of years it was normal in pretty much every culture on the planet..... and still is to this day.
