This is quite an interesting piece

I am also not a religious person (I was brought up in a RC household), and I welcome the equal rights for same sex couples - however.
Why would a same sex couple want to insist on their rights to be married in a church, if it was specifically not allowed? How would anyone feel if they went through with the ceremony, knowing that the majority(?) of the congregation did not support what they were doing?
Is it any different to me going to play golf at a private club, and then decide to rebel against the dress code in place, knowing that this would probably result in me being asked to leave and never return?
I cannot understand why gay people do not start their own breakaway version of the Church of England/Roman Catholic Church, if they want to do things differently, after all there was a rather famous split in the church nearly five hundred years ago.
I regard religions in much the same way as I regard clubs. Have a look around, read up on them, study the rules, weigh up the pros and cons, and then join one (or maybe start one yourself) which suits you.
