If you find it offensive if *anybody* references family in a derogatory manner, then if CH is *anybody* you must find it offensive. If you do not find it offensive if CH references family in a derogatory fashion then we can only come to one of two conclusions:
1. CH isn't *anybody*.
This opens up a whole myriad of possible tangents. From CH is *nobody* to you are an all powerful being that gets to decide who is *anybody*.
2. You apply your alleged "principal" on an "as needed" basis.
