Wow. It's a group conversation now.
First off, let me say that I've been speaking from a general perspective that many Christians have on homosexuality. Like I've said before, I'm on the fence with the issue and can see both sides. I'm still forming my own personal belief on the issue.
That said, from the general perspective I was using to explain where some Christians come from, it's getting into the apples to oranges debate. I understand how you guys see it, but they don't see it as something homosexuals are born with, so therefore it is a sin to them. You can't say they're hateful or discriminatory when their opinion, no matter how wrong or right it is, differs from yours as far as why people are homosexual. If they believed they were born that way AND continued to call it a sin and/or were to discriminate, then yeah, there's a bigger issue to deal with. However, if they simply see it as a sinful lifestyle, then at best (or worst) they're ignorant. I don't think that equates to hate, especially if they're ultimately looking for that person to find salvation from their sins through Christ, like all of us need. Then they're still just hoping for the best for that person. Does that make sense?
I think that's some of why there's so much tension and a lack of meaningful dialogue between the two sides is because both sides are failing to understand that the other side has a different definition of homosexuality and it's a view they hold with some conviction. Then there's name calling comes from both sides.
Now, if they're discriminating regardless of what they believe, that's wrong. If they're using the term sin when they believe that's what it is though, I don't see it as hate. It may be wrong, but ultimately they want that person, I would hope, to find salvation through Christ for their sins and see that it, as well as every other sin, is detrimental to their lives. Again, whether it is sin or not is the truth we all need to arrive at through open minds, prayer and positive discussion.
