It goes a bit beyond “cultural disrespect” if someone copies a name tattoo, for example. Depending on the person you could say it would be like stealing someone’s face. And since in our culture tattoos are earned, someone just inscribing tattoo that indicates someone as a person of importance, such as a military commander, on themselves is well, something I’m sure at least many can relate to us as a bad thing. “Stolen valour”, I believe is a term I’ve heard used in the Federation.
Now of course we can argue that do such people deserve a sound beating for such offences, but I’m sure we can all agree that it’s immensely disrespectful.
