I strongly agree with the hon. Lady. This shows that people in Northern Ireland simply do not have the same rights as those in the United Kingdom, and that is something we should act upon.
There is a case, on its own merits, for introducing same-sex marriage, and I just want to say to the Committee that, frankly, this argument has been won. It has been won in the country and it has been won in this House.
One by one, the arguments against this reform fell away. First, there is no compulsion involved. The legislation that we introduced in England and Wales protects religious freedom. Churches are not compelled to introduce same-sex marriages in their own institutions. That is a matter for them. No individual is compelled to enter a same-sex marriage. There is a very simple remedy if someone does not like the idea of same-sex marriage: they should not enter into one; it is not compulsory.
Secondly, why should we not allow people to enter into an institution by which they will demonstrate a lifelong commitment to each other and make that commitment in front of their friends and family? What harm is done by this legislation? We as hon. Members know very well that we pass laws and vote for things every day that make people profoundly unhappy or that irritate them. We put on taxes, we restrict freedoms, we do things that irritate sections of our communities, and we do these things because we think they are right. It is not often that we pass legislation that has a single effect. The single effect of the legislation for England and Wales that was passed six years ago in this House was to make people happy. It was to allow people to enter into lifelong commitments that brought moments of enormous happiness to them and their families.
That is why public opposition to same-sex marriage has continued to fall away. I have enormous respect for those of my hon. Friends who voted against that legislation but who have now admitted that they were wrong. One by one, Members on the Conservative Benches have stood up and said that they were wrong to oppose the measure, just as some Members have said that they were wrong to oppose civil partnerships. They have seen that the legislation has been an unalloyed force for good.
