In many ways any blog post on Cardinal O’Brien’s calls for a referendum on the legalisation of same-sex marriage should be a short one. There are few good reasons, if any, for such a plebiscite to take place.

Granted, there were 80,000 responses to the legislation consultation; more than triple the number for the independence referendum’s equivalent, but if that was the model for such decisions then we’d be having referendums on the death penalty and other frivolous matters every other year. If any group of people feel strongly enough about this particular issue, stand for election and let democracy run its course.

That said, I have strong misgivings about the lack of a mandate that existing parties have to bulldoze through legislation that wasn’t in manifestoes: the increasing privatisation of the NHS and the increase in tuition fees (both rUK) to name but two examples. However, I have no such qualms when a Government is doing the right thing and making the nation a fairer place to live. If there’s enough disagreement across Scotland against this, let the streets be filled with it. Speak now or forever hold your peace, if you will.

Cardinal O’Brien on his own has as much right to a leading opinion in this debate as a bishop has to a seat in the House of Lords. It is a legal matter and not for the church to involve themselves in.

Not that I’m the happiest, let alone the clappiest, of people on the wider issue of gay rights. The ‘real’ debate, and controversy, for me is around the issue of families with same-sex parents. If I was to be born again and was given the choice of having same-sex parents or the more ‘normal’ mother-father situation, I would without a doubt choose the latter, all other things being equal. That, in turn, must mean I have reservations around surrogacy and adoption from same-sex parents, though I shan’t try articulating them here as, mercifully, the issue at hand is simply the question of marriage.

The SNP, and all parties of the Scottish Parliament, need to stay the course and not be swayed by the unpopularity the correct decision in this matter will attract from some quarters. Needless to say, this is a test of Salmond’s strategy of ‘big tent’ nationalism as the SNP pushing through equal marriage at Holyrood will no doubt see many small-c religious conservatives be less disposed to voting Yes in 2014. That, for me, is an immaterial number and anyway, not every decision between now and Autumn 2014 need be viewed through the distorting prism of Scottish independence.

This is one such decision. Indeed, it’s a no-brainer.
