Here are my 
I see the Bible as sort of map, which might help you find your way to whatever destination you wish to go.
Now, this map was drawn a long time ago. If you look at a geographical map that was created at the same time you might find it quite inaccurate compared to a map that was drawn today with the help of satellite images and what not. That doesn’t mean that you won’t be able to find your way from A to B with the help of a map that is 2,000 years old, but the likelihood that there might be some inaccuracies is rather high.
What do you want from a road map? Basically, your location, your destination, and how to get from the former to the latter. On a map drawn 2,000 years ago, for example of the Roman Empire, you might be able to find your location, let’s say Rome, and your destination, let’s say Carthage. Now the problem is what’s in between, like roads, harbors, etc. Over the last 2,000 years many things have changed. Maybe not the location of your starting and end points (though Carthage is long gone), but what is in between, and of course the modes of transportation. If you look on a very old map, you won’t find airports, for example, so you might decide to take the land route first and than the ship across the Mediterranean. Someone who would plan a trip by only looking at that old map, perhaps with the help of an ancient-map expert, and not consulting other sources of information that have become available in the last 2,000 years would be rather silly, wouldn’t he?
Now, the Bible is not a road map, and your destination is a bit less precise (Heaven?). But what the book definitely cannot provide is information about important factors that could influence your journey, in many ways, technology for example.
How do you make decisions in your life relying on a map/guide that does not give you specific advice on how to decide in situations that would not have occurred in ancient times? You can rely on the help of “map experts” (pastors, priests, scholars, the Pope, etc.), but what if these experts contradict each other and the common ground they can agree upon is so small that you cannot base your decision on that? Now you have to choose, one sect or another, one interpretation or another, for example a sect that sticks to every single word in the Bible, believing that it was written (and translated) with the help of the Holy Spirit and therefore must be all true; or a sect that interprets the scriptures more loosely (cherry picking the things they like and ignore the rest basically).
Is the Bible anti-gay? Unless it says word by word “Being gay is wrong” or something along those lines, it’s all up to interpretation of the words that are available. Like with an old road map, you have to do a lot of guessing. And one’s you open the gates to interpretation, it becomes everyone’s guess really. Depending on your background (education, people around you, personal experience, etc.) you will interpret those words in certain ways or you will listen to someone you trust who interprets them in his or her own way. And there will never be a final official answer to that question, unless Jesus or Moses, or someone with that kind of authority, appears and makes a final judgment.
For me the Bible gives me some general guidance (love and forgive) and some strict rules (don’t kill other human beings), but not much more. And I think that is already quite a lot. If everyone who says he/she is a Christian would just do those three things, LOVE, FORGIVE, DON’T KILL always and without exception, we would live in a very different world.
When it comes to homosexuality, how about focusing on the first and indisputable task asked from any Christians, LOVE. Whether you are straight or gay, love your fellow human beings, without exception. Don’t hate.
