>Did you intend to be offensive, or was it just the easiest way to describe a certain group of people?
Did you find what they wrote offensive? It isn't clear.
If yes, what aspect of their writing (what particular phrase or word, when considered with/in the appropriate context) was offensive?
If you in particular didn't find what they wrote offensive but believe that others might find it offensive, what aspect of their writing (what particular phrase or word, when considered with/in the appropriate context) do you believe that others would find offensive?
