On the contrary. To associate those letters with a decapitated head goes beyond disrespectful.
Imagine being tied to a pole and whipped more than 100 times until your skin was in shreds. Then having your arms tied to a 100 lb crossbeam that scrapes against your fresh wounds. Imagine falling under that weight and having people spit on you and soldiers whip you some more. And, imagine having nails driven through your wrists and feet before being raised upright to die. In order to breathe, you must press your weight down on your pierced feet in order to elevate your body enough to expand your rib cage to suck in some air. Imagine your mother standing below, looking up at you, in utter helplessness.

I don't ask you to believe; I ask you to have some respect for those of us who do.
