*pulls on thicker skin* Whew. Ok, here goes.
I have used this line on this forum. I used it because I asked for opinions in a thread and after the thread got about a page and a half long, my indesicion about what I asked about went away. When I STARTED the thread, I didn't know how I felt about it. After reading several posts from folk here, and thinking things through, I made up my mind about it. And I made a post to this effect, just so people reading would know that I had done so. AFTER I made that post, I did defend my newly decided decision and I did get a bit snarky with one poster because I felt like they implied something about my parenting skills. I realized I was snarky and apologized. But another poster then decided to tell me I had only posted for support, not opinions. I can see where it may have looked that way IF YOU DIDN"T READ THE WHOLE THREAD and saw where I posted about reaching a decision about the whole thing. I pointed that poster to that post, and then another when it came up again. When a third person again latched on to that theory,assuming that I was just posting for support rather than opinions, and that I was now angry that people disagreed with me, I was rather frustrated because one of my worst peeves is people not reading posts fully before they post. So I posted the line. And fully admit is was me trying to find a nice way of ending the conversation without saying 'shut up'.
I've read where several people on this thread think it's wrong to use it here but I disagree. I don't see why if it's perfectly appropriate to use in life, it wouldn't be appropriate to use here. After all, we're all human and we all get our backs up occasionally, and we all make mistakes and need to be called on them. Why would you advocate something to others but not to yourself? Why would the line be ok and proper and NOT rude in RL but wrong here? Are we special because we post here? I don't think so. I know I am just as capable of making assumptions here as I am in RL, and I try to not be offended when someone calls me on them. I've apologized more than once on this board when I realized I was wrong. And someone using the line is a lot easier to swallow than someone telling you what a rude idiot you are.
Of course, this is just my opinion, and I may be wrong.
