I have no problem with people having and following their own faith or following their personal moral compass and making their own choices - in fact that is what I am advocating. However, when organised religion isn't involved in paedophilia I might start listening to their institutional advice.
I know many people of many faiths that will be voting on both sides of the question - as individuals we should be encouraged by the freedom of religion or indeed to have a religion and the freedom of choice that we have. As for what is a sin why does the Church single out homosexuality when the Bible only singles out one sin.
“I promise you that any of the sinful things you say or do can be forgiven, no matter how terrible those things are. But if you speak against the Holy Spirit, you can never be forgiven. That sin will be held against you forever.”
I'm not trying to be a smart-arse but the Bible is also against divorce, insists on women covering their heads in Church (and that's the New Testament). I haven't seen the Church recently advocating that people should not work on the seventh day or calling for death penalty for those that do.(Old Testament.
The bible is full of the crazy. Fun stuff from

There's a lot in there that makes sense, and in any time we'd agree that they're wrong. In large part, they're wrong because they harm others.
But others are quite obviously not needed or are forbidding things that are nobody else's business, or worse punish someone for something they can do nothing about or even a victim of a crime!
Anything from having a cheeseburger to having fish fingers is out, eating crackling (or the rest of the roast pork) is out, having a foreskin is out, a woman whose hymen breaks riding a horse our using a tampon is out, being raped while an engaged virgin used to be punishable by death!
If your clothes are woven from two different cloths, if you plant two different types of flowers in your garden, if you cut your hair and shave you're toast.
So we already apply modern standards of morality. We already pick and choose, according to moral codes for ourselves.
There are things that we can deem to be absolutely wrong, and forbid them - murder, rape, lying, theft, etc.
But for many other things, we make a value judgement, weighing up whether there's a victim and weighing up whether there's a social cost.
We bring to bear what we know - this is what knocks off a lot of the food things, because it's no longer hard to ensure that pork or shellfish (for example) is safe to eat, because we can prepare and store it safely so people don't get sick.
There's no law against individuals choosing to abide by the majority of these principles insofar as it doesn't affect anybody else.
If you don't think people should eat pork for religious reasons, don't eat pork, but it really doesn't affect you if others do.
If you don't think people should cut their beard for religious reasons, don't cut your beard, but it really doesn't affect you if others do.
If you don't think gay couples should have sex (or get married), don't have gay sex or marry someone of the same sex, but it really doesn't affect you if others do.
