Not even close. Cosby's victimization of women spans decades. A good portion of that victimization included drug-induced or 'date' rape. Trump has raped no one. Not even the recent volley of vexed victimized vixens has accused him of rape.
I would extend the difference to include those who are subordinate to their abuser in some way--e.g., students, employees, wards of the state, nursing home residents, etc.
