Nah, you don't get to run away from this. Christianity is fucking shit on Lgbt rights, and it's not just some nutjobs. The Church of England is still having fits about blessing of gay marriage, or gay bishops. The Catholic Church stills considers us as 'intrinsically disordered'. And let's not talk about the evangelical churches in the states.
You don't get to stand there and throw a 'no true scotsman' statement out about Christianity not judging people, because that's *all* the religion has done for many of us. And it's perfectly fair to be suspicious and wary of someone so tightly wrapped up in their religious beliefs when every example we have is of people like that being dangerous and bigoted.
As much as I enjoy taking potshots at religion when it stands in the way of progress, the UK is leaps and bounds better than many places.
I posted this earlier in the thread, but attitudes since the 80s have vastly improved ~

The trends documented in the long-term survey data presented here are clear and consistent. Across different aspects of the topic of same-sex relations and equal rights, and using different questions from social survey series, there has been a marked liberalisation of opinion amongst Christians (Anglicans, Catholics and other), as well as amongst those with no affiliation. Whereas often large majorities of the religiously-affiliated used to express disapproval of same-sex relations, or disagree with the right of same-sex individuals to be able to adopt children, hold particular occupations or get married, such opinions have steadily decreased over time and more recently these views have been expressed by minorities or less emphatic majorities. On more recent evidence, those with no religion still tend to express lower levels of disapproval than do Christians, as was usually the case in the earlier surveys.
You'll never eradicate bigotry around religion, as the doctrines are riddled with it. That's a fools game if that is anyones ultimate goal. The best thing we can do is keep the government separated from religion, so it's solely a matter for the people, and with the people drag them kicking and screaming towards progress.
Subjecting people to being around the change they fear is the best disinfectant. For many religious minds that have been wired the way they have/indoctrinated, a lot of bigotry is like a phobia. I was rambling on about disgust sensitivity earlier in the thread, and not to do it again, but it comes into play here too (a lot of perceived "disgust" surrounds two men kissing/having sex). However, subjecting someone to exposure to their phobia often mitigates it. So, gay marriage passes, and the population gets exposed to it. What happens over time? Well, people start to realise what happens when gay people get married is... they get married. No lighting bolts from god? Nothing serious changing around them other than people being happier? Well... okay. Sure, it can take years of exposure, and in some cases, many still stay bigoted as fuck behind closed doors. Many do change though, and changing who we can is the best form of success possible for humanity. We will never completely eradicate bigotry, whether its religious or born from other sects/intolerance/cults/etc, but we can marginalise it and important, keep the government separated from the Church(es).
