Tough question. I'm so new out of the JW thought processes. But here is my take. While I am not a fundamental Christian (anymore) and I am very liberal (you do what you want, I do what I want), I still feel plagued by my personal feelings/training on the matter. Sleeping around and homosexuality are up there with lying and cheating to me.
On the upside, I am firmly resolved to never let that cause me to look down on anybody. I have certainly been the fool of the WT for many years and people could look down on me. I am short, overweight. My wife and I are different races. People are all different. Just because I am still uncomfortable with certain moral standards doesn't mean that I need to apply my thinking to other people. You don't need my approval and I don't need to rid the world of people who live differently than me. (Hey, that's not WT thinking)
