The site guidelines don't ask people to take the "strongest plausible interpretation" (emphasis added). That's not quite the same thing. I didn't see a plausible interpretation of your comment that wasn't unduly personal—hence my reply.
Interpretation depends on past experiences and associations. Since everyone's are unique, no two people will always share the same interpretations. It gets worse when all we have are little bits of text to understand each other through. For example, if you had spoken those words and I had heard your tone of voice, it's quite possible I would have interpreted you differently.
On the other hand: you can't go strictly by intent, either, because intent is internal to the person whose intent it is. No one else has access to that (we're not mind readers) so the burden is on the commenter to disambiguate it.
