In my opinion, there's one aspect of the current debate that I haven't read or heard. 

I believe that most thinking adults on both sides of the debate would agree that human sexuality is complex - some would say very complex. 

I'm also confident that many older citizens will agree that life experiences and personal reflections, made it easier to change one's decision as to what tick on the ‘ballot paper’ from ‘yes’ to ‘no’, or from ‘no’ to ‘yes’.
