The nail is driven home in your latest cartoon (as I must position our metaphor). In the UK, having met with our local member of parliament last week on the government consultation on marriage equality, he said that it is the 'complimentary nature' of man and woman that makes marriage sacred, unique and immutable. If I must reduce his argument to its essential 'thrust', parts is parts. Are we really at this point in the Great dictionary debate?
"The course of true love never did run smooth" and certainly not exclusively straight.
