Now me, I've always considered Mind Rape to be defined as a form of psychic torture; Forcing someone to expect a traumatic event mentally, forcibly digging up past traumas and forcing them to relive it, or driving someone insane using mental pressures.
When Rogue made Bobby relive getting his teeth drilled without novicain in ultimate X men? That's a mind rape. When Agent Mist sicced his hellspiders on the Billberg Sci-Fi club in Fans!? That is a mind rape. What Sarda did to the dark warriors in the latest 8 bit theater, that is a mind rape.
The above scans? Just telepathic interrogation. Probably sketchy under the laws of the land, but unless the victim is notably traumatized from it, I doubt it is mind rape (although Charles did threaten mind rape on Crossbones in the second example).
