Democratic Primaries

Here's the original post NJ is taking me to task over (which had been subsequently edited):

I'm putting it here because NJ seems to feel I'm trying to pull something by having edited away a perceived personal insult (she said, "it gets the message across without having to worry about the obvious repercussions or consequences. How clever!" "Editing is just an admission of guilt" etc. ). So now people will see it, and I hope people will see I was not being duplicitous. My edit was made, not to remove an insult that I didn't want to be held accountable for, but because I realized she was probably referring specifically to something mentioned earlier in the thread (even though it was not mentioned in the post I was actually replying to), which prompted me to then put up a different reply instead.

I'm curious to know what people here think about this. Of course, I can't change how NJ feels about it, but I don't want to do a lame "I'm sorry if you were offended" non-apology apology either... if I genuinely wronged someone, I'll offer a genuine apology. So I'm curious to see if I'm truly missing something here. Was this really an egregious personal affront? Do I appear to be calling anyone a liar, or stupid? I don't see a personal insult in saying that I think an assertion is likely to be bullsh*t when no support is provided for it, this does not seem to me to be beyond the pale for acceptable DU discourse. Am I really off-base here?
