I hate to break it to you, but my post wasn't about you. You should know by now that I have zero problem with telling you exactly how I feel about you, with examples and without pussyfooting around and in a language that's more than a little direct and not really open to interpretation. Ben asked the question, and as I've got an opinion on it, I answered. I largely agree with alisdair's thoughts about words and accountability.
I've had a problem with people deleting or heavily changing the nature of their posts since I've been here. Bluntsie used to do it all the time, as did a few others who I'm not gonna name because I don't want to bring up dead and burried shit. I've seen you do it a few times tho, come to think about it, but nothing major (so it changes the nature of the point youre trying to make etc), but perhaps (given your quote above) I should start paying a little bit more attention to your posts again, because it sounds like you're confessing to doing it quite a bit.
Also, whatever comment of yours you're talking about that you regretted, so deleted (I have no clue which one you're refering to)... but why not just take it back by posting a retraction and saying 'sorry, I was a bit harsh there ... yadda yadda'? Deleting comments like that (unless the other person has requested it and you've agreed by request) don't necessarily look like it was regretted, it often just gives the impression a poster is trying to look a certain way, or manipulate other people's perception of themselves. Even an edit with a 'comment removed for X reason' would be more truthful than a deletion.
It's like alisdair said, accountability and responsibility for words. I've got a big thing about that, it's something I see as being very relevant and something we need because it generally helps improve relationships and gets people to think much more about what they type and submit before hand. Take responsibility for the words you type, and if it goes wrong somewhere, then do the right thing and either apologise, or retract and offer an explanation or something. Erasing it is just the easy way out and is very open to interpretation.
On a separate note, while I'm talking about accountability & responsibility for words, one of the main issues I've had with you has been linked to that, and a whole range of stuff you've written tbh, but I'll leave that there for now because I doubt you're interested in hearing about that.
