My parents and I feel largely the same about the issue of homosexuality. That being said, they do not personally know any g/l people, so I think the idea is more of a concept to them than a situation with a face as someone else put it so eloquently. I, however, do have several g/l friends, so the issue is more real to me if that makes sense.
As a Christian, I do view the behavior as a sin based on the Bible. However, I absolutely cannot tolerate it when people jump on the judgment bandwagon and attempt to point out g/l people as some sort of really bad sinners. It seems to me that people who are so quick to judge others and speak to them in harsh tones are avoiding looking at their own lives and worrying about their own lives first. I cannot and will not tolerate people using hate-filled speech about another person. The way I see it is that were all sinners, so who am I to try to point out somebody else as being one. Im going to focus on loving all people, regardless of their lifestyle, and I hope they will choose the same for me. Ill let God worry about the judgment. I think its easy when you see yourself as not being perfect to love othersif were all in the same boat there isnt as much room for judgment.
FWIW, I support legal unions for g/l people so they have the same access to healthcare, survivors rights, etc. as a heterosexual couple. I dont support calling it marriage per se. I think that all people should receive legal union paperwork (whether gay or straight) that gives you the rights of a married couple today, then let churches handle marriages (each church deciding who they will or wont marry according to their beliefs). Sorry, I guess thats a bit of a tangent.
