Indeed as a reference it is offensive. I am however getting tired of our societal verbal "walking on eggshells". I believe we are collectively too quick to take offense, and in part I think this comes from this type of and all too frequently repeated course correction. I am poz. It is my choice whether I am going to be offended when someone asked me if am clean. If in person my response would be "yup, douched awhile ago.".
We are in a society of intentional ignorance. And most of those folks don't give a crap about how this poz guy feels about much of anything. I don't take offense to the other epithets classically tossed my way fifty years ago either. F word or Q word my response is "yep!", which after moments of stunned silence has gone further in effecting course corrections.
