Good on Margaret Court, page-106

What has gay marriage have to do with your hypothetical situation of a grandfather having a sexual relationship with his grandson ?
Surely the issue is with the relationship , not about the piece of paper ?

To use your logic , what if a grandfather decides to have a sexual relationship with his 18 year old granddaughter ? Because they aren't of the same sex does that make it ok ?

I welcome the discussion but using shock tactic examples which are irrelevant just doesn't cut it .
