Jesus did not address teh gayness. Paul did but in the same breath, told people to be kind to their slaves. There are tons of instructions from Paul, a mortal man, that are referencing the issues of the times. And in that particular time and place, you would be stoned to death for washing your camel on Sunday or saying "That lovely piece of halibut was good enough for Jehovah, Jehovah, Jehovah."
I consider myself a Christian but not one that takes every word of the Bible literally, especially when 90% of it is man's interpretation of how they thought things should be during a time period and an area of the world where thinking and things in general were and still are as F'd up as it gets. Jesus laid out a pretty simple plan for living a Christian life, which all centers around treating everyone around you the way you want to be treated yourself.
That's about as deep as I get. And while there are a lot of issues in the world that I take a stand against, this isn't one of them. I don't think it's a lifestyle choice and as for it being a sin, that's not my concern. Just because Paul said don't have ghey butt secks, doesn't mean that's what God or his Son thinks. As for them having the opportunity to get married and be entitled to the same rights as any other married couple, well, that doesn't concern me in the least either. It doesn't affect me in any way. It doesn't infringe on any of my rights and as far as I can tell, doesn't trample on any rights any of you have.
I just don't see the problem. It's not for me to judge and if it truly turns out to be a sin that will keep someone out of heaven, then I guess that's their problem. If you're murdering people or stealing from folks or selling drugs to kids etc. I got a problem with it. If you're attracted to the ghey butt secks, whatever.
BTW, I'm married, have 2 kids and I'm 54.
