Well that was disappointing.
What gives you the right to demand that people in any kind of mutual' date=' adult relationship "justify" themselves? And even if they did, what gives you the right to determine the standards against which people will be measured?
If one is going to take your view, then [b']anyone[/b] in a non-reproductive relationship is "doing something obviously wrong".
Taking the "nature intended" approach is doomed to failure, for the reasons already mentioned.
Well, see that's where the problem is. Asking for the right to marry is not working outside the bounds, it's asking to be allowed to work within them.
The laws of the USA expressly forbid discrimination. The only reason gay people can't marry is because of fundamentalist crackpots, and the millions of people with uninformed opinions like yours*.
