I wouldn't worry too much about wether what you have to say is perceived as being negative / offensive, you can only offer up the truth as you see it and leave it at that. Even if someone takes a post negatively it still might put the idea of what you're trying to get across in their head.
I certainly didn't get sober by people being nice to me about it. Sometimes a good verbal slap was exactly what I needed!
I know I haven't posted alot on here yet but I'm really grateful for all the advice offered up, it's all food for thought and you would have to work pretty hard to offend me
