Today Is...Same-Sex Marriage Legalised In UK

Love and marriage goes together like a horse and carriage according to the old song which is fine until it is between two people of the same sex but if it isn't an XX and XY Chromosomes receiving the blessing then the religious folk start angrily shaking their rosary beads and stutter that 'MARRIAGE IS A 3,000 YEAR OLD SOCIAL CONSTRUCT BETWEEN TWO PEOPLE OF OPPOSITE BIOLOGICAL SEX'.
I have never got Religion or the religious at the best of times, to me if you believe in a God then you obviously haven't given it enough thought, but more than anything i don't get the refusal to accept same sex marriage.  
As long as two people love each other, why should it matter if they are of the same sex and if your only objection is the question of sex between same sex couples, then why is what they do in the privacy of their own bedroom any concern of yours? If you were so obsessed about sex between a man and a woman then there is a name for that, you would be a Pervert.
Homosexual weddings were commonplace in Rome between the first and third Centuries regardless of whether the bride and groom had the same sex organs, even the Roman Emperor Nero married men in wedding ceremonies but it wasn't until the eighth Century that the Church realised they could drag God into the union and the Catholic Church made it so that for a marriage to be 'legal', it had to be conducted by a priest.
The early Catholic and Greek Orthodox churches even had special documents for homosexual wedding ceremonies, the “Order for Solemnisation of Same Sex Union and the Uniting Two Men documents where the priest would grant the participants 'grace to love one another with the help of the Holy Mother of God and all thy saints.'
The actual wedding sacraments were not written into canon law until the Council of Trent in 1563 although the church still held that men were the head of families, with their wives deferring to their wishes and the bride’s identity was absorbed into the grooms, so the bride would give up her surname as a symbol of surrendering of her identity and the husband would become the representative of both people.
It wasn't until women won the right to vote and became a full citizen that that the institution of marriage underwent a dramatic transformation to resemble what we know today which is the union of two people so far from protecting a 3,000 year old construct of men and women, the Bible carrying crowd are actually protecting a 1,300 year old social construct when it became officially the religious union of two people regardless of whether they were the same sex.
