I'm failing to understand how a lesbian queen and a queen giving birth through artificial insemination is even related. That's just weird. Was the guy suggesting if a queen married to a man, say with sperm issues, who chose to use artificial insemination would somehow produce a child that wouldn't be considered royalty? Even despite being born of the queen? What an idiotic comparison.
Although, I like the father/son marriage thing. That's an interesting thought exercise concerning modern laws. Kind of silly, but interesting nonetheless.
He was just trying to come up with the most offensive sounding (to his conservative constituency) examples to shock.
The father/son marriage thing of course could not happen for the same reason we don't have father/daughter marriages today: the laws have restrictions on close relatives marrying.
