Ok, I've only skimmed this thread, so if I repeat somebody please excuse me.
From what I understand, fornication is a sin, perhaps not because of this, but this is an example I was given. In Genesis, God made Adam and Eve just for each other--she was his compliment and the two paired. This is the Bible's first "marriage." And in there it says something to the effect of, "And for this reason a man shall leave his family with his wife and the two shall become one flesh." Now, in I Cor. 6:16, a man "became one flesh" with a prostitute, so it's pretty clear what is meant by that phrase. That's why we believe you don't have sex before you're married, because God used A&E as an example of what marriage should be--you are paired up for life AND THEN have sex. It's not in some list of rules, but this is mentioned several times in the Bible so it's taken as such.
Having said that, I do believe fornication is wrong, therefore I have no intention of doing it. I believe it's wrong when people lose their virginity before they are married and I'll say so if I'm asked. Also (shoot me if you must), I go by a different rule for casting stones. I don't see it as no one can "cast a stone" at me if they've also done wrong. Just be prepared when I throw it back. So I don't think it's all that wrong for divorced people to talk about what you've done, that's their right to feel that way. But when you point out all of their dirt, they better not say a word about it. But honestly there is a disclaimer: if you didn't ask them what they think, they shouldn't be talking about it anyway.
