On Tuesday, MPs will debate the controversial same-sex marriage bill. I and scores of colleagues on both sides of the House will vote on what is one of the most intolerant pieces of legislation that we shall have the displeasure to debate. Naturally, I respect those with different views, but I do suspect the motivation of some. 'Equality' has become a religion in itself in this country and the word is applied all too liberally to every aspect of our lives, with damaging consequences. I remember Tony Blair swearing to destroy 'conservatism' when he was first elected Prime Minister and for some on the Labour benches this bill is another nail in that coffin. I am a Conservative and my instinct is to conserve, unless there is good reason not to. To me there is only one true definition of 'marriage' and this act can only be between a man and a woman. It is sacrosanct and a founding principle in this country, based on the Christian faith. To tinker with this is unwise in the extreme and we have no mandate to do so. The Prime Minister appears not to listen to objectors on the basis he believes this move will make the Party appear more tolerant and compassionate, and presumably electable. A recent ComRes poll reveals that the gay community itself is not taken in one jot; in fact the opposite is true. Many gay people I have spoken to do not want to redefine 'marriage', happy as they are with civil partnerships. They also respect the institution for what it is and not what a politically motivated Prime Minister wants it to be. I am told by those close to the Prime Minister that he believes the issue will just die away after, and if, the bill is passed. I can tell Mr Cameron it won't and millions of people in this country will not forgive him for using his office and a flawed Coalition to push such a fundamental change on our nation when few have called for it. The unintended consequences have not been considered, either, and many of us see churches and schools dragged through the courts as equality and human rights' legislation is used to bring opponents to heel, whatever 'locks' are in place. I shall speak - if called - on Tuesday and vote against the bill. We will, I suspect, be defeated and another bastion of our wonderful country will come tumbling down. What a terrible and shameful tragedy.
