I am proud that the UK is a progressive nation and I certainly include Gay marriage in this. I'm certain that within a generation this will be a none issue and rarely ever mentioned.
There is a difficult issue around the treatment of the opponents of progressive society and those that are opponents certainly feel victimised. However, it's not a black and white issue.
We pretty much would all agree that not all opinions should be respected. As a society we don't respect racist opinions; we don't respect the opinions of suppressors of women either. People that hold these opinions could also feel victimised for having their view but I'm not sure many people would feel that this means that they are facing genuine oppression because people are intolerant of their intolerance.
These are obviously extreme examples. However, in 2014 as a society we don't respect homophobia anymore either. Now I'm not saying that all opposition to Gay marriage is homophobia, at least knowingly. I personally think though, that a large majority of it does come down to what is essentially a form of homophobia. I've had many a debate (including with saintslass) and I've yet to hear a real argument against it that isn't basically a pedantic semantic or historical argument that ignores the reality of modern marriage, where we already have a mix of religious and non-religious weddings. If it is just a semantic argument then why is there the vehemence against it? Jesus was far more clearly against divorce yet we don't see swathes of people signing petitions to see this repealed. If the Pope decided that divorce was allowed I suspect most Catholics would just accept it without little more than grumbling. Whether they like to admit it or not, I suspect that a large majority of anti-gay marriage advocates still see something wrong with being gay and this is what is largely behind this opposition. They might not hate gay people or individuals but I suspect they wouldn't feel comfortable if more people started becoming gay. This is why I'd still call it homophobia.
I have sympathy for many of these people because I don't think they are at all bad people. Their views are just outdated and based on flawed religious traditions. The clash comes from the fact that the days when religious people can tell non-religious people what to do are over. Progressive society is basically about allowing people to do as they please as long as it doesn't cause harm to others, it is about giving everybody equality of opportunity and not being discriminated against because of something they were born with. Too often religious society has been about imposing their beliefs and prejudices on the rest of the population even those that don't accept their beliefs. Allowing something that religious people find distasteful even though it does not directly affect them is not the same thing.
This reflects the way modern society is; religious people's rights to practise their religion as they want are not restricted it is just their ability to impose this on others. They can also hold whatever opinion they want, they just cannot expect everybody to automatically respect it anymore.
