Yes, actually - we all, at some point, get to be the final arbiters of deciding whether what what we said was offensive or not. (which I suppose also means that everyone else gets to decided to the final arbiter of whether they're offended or not - a right some have proven time again that they're not giving up)
So again - I guess my bottom line is, if I didn't mean to offend a person, and they want to get offended and make a big damn deal out of it - they can go right ahead. I'm not changing what I do just to keep up with the most offended person in the room. :-)
I'd like to give you a mantra that I try my best to live by. "Judge others by their intentions and yourself by your actions". That is to say that other people can and will interpret your actions in ways other than how you intended.
I do actually live by that myself, but there's also people who just can't give anyone a break ever and want others to defer, defer, defer to their whining and complaining. I allow myself to draw a line too. For every time there is a season. :)
