Asgara may yet answer you but I'll try to explain it. You are using the right Reply button for the wrong post or message. You often hit the Reply button for a post farther down than the one you mean to reply to. Yes, usually it's not hard to figure out who you are answering, but once you did criticize what I wrote thinking it was what someone else wrote and that never did get straightened out.
Also, the quote codes are a very good thing as Asgara was trying to explain. YOU choose exactly what you want to quote, it's not automatic so it won't quote more or less than you want. You use the codes yourself, type themj in yourself and put the quoted message between them. It really does help make posts more readable.
Also, just for myself, though others have mentioned it too, I don't think quoting a lot of scripture helps you get your viewpoint across at all. We can all quote scripture but what counts in discussion is our interpretation of it.
