Heck, it was Roddenberry who gave us rogue Starfleet captain Ron Tracy and deranged ex-girlfriend Janice Lester, in "The Omega Glory" and "Turnabout Intruder," respectively. Both scripted by Roddenberry himself.
My view of Roddenberry's vision is we should be like Bruce Lee and take the good while leaving the bad. Like the fact he didn't think women could be starship captains (but did think they could be 1st officers--so...progress?)
