I didn't see Rebuckster's response, so I don't know what he/she said, but I thought your response to the original post was fine. There was nothing wrong with what you said. It was your opinion, offered up respectfully as someone who lives with this condition. I mean, if the OP didn't want opinions, why did he/she post in this kind of forum to begin with??
Please stay. Don't let one bad thread ruin what is otherwise a really good place!!
I don't think I can fully comprehend what the non-diabetic parent of a diabetic kid is going through because I haven't done that myself.
In some ways, as a T1 since I was a kid myself, maybe I have it easy compared to the parents.
But when it comes to sham cures, I'll come down hard on the charlatan every single time. I don't think you have to leave, because of what some charlatan was trying to sell, if that was the issue. I don't remember seeing the problem posts in question, but if you were coming down hard on a scammer, I don't have any problem with that.
...Another vote for you to stay. It's SO easy to have mutual misunderstandings online, and we all have our hot-buttons and sensitivities around diabetes that make those misunderstandings even more likely to happen, and more painful when they do. I hope when the sting from the interaction fades you'll decide to stay with us. :)
I hope that you'll stay, also, even if you need a break for awhile. The newbies on here benefit so very much from the knowledge and experience of everyone who has had diabetes for a long time!
I hope from everyone's response you realize you are a valued member of the community and that you will reconsider your decision. These types of things can happen easily online, sometimes the best thing to do is to ignore another's post. Others here have benefited from your knowledge and experience and will miss your input if you leave.
