Dear Saltpetre,

Our society is made up of more than just "conventional couples" - and that's the whole point. Anyway, for me this topic has now run its course.

Me too, atypical relationships form whatever the legal constraints, where there's a will there's a way.
I can't see widespread acceptance of a re definition of a marriage on account of (possibly) a few thousand people who may want to take up the offer.
It's, as I said a trivial issue when all is said and done, what's more it takes the gaze off the other "projects" that flock of warmongering vultures currently roosting on parliament hill are cooking up.
