I think Rick Berman and Branon Braga in their career prime would've more likely gotten dragged through the mud, ala Singer and Whedon, as well.
Let's get a few things straight here.
1) Rick Berman sexually harassed and retaliated against multiple women during his tenure as head honcho of
Star Trek, including shaming Terry Farrell at a costume fitting by demanding to know why her breasts weren't as large as he wanted them to be and comparing her breasts to his secretary's:
2) Whedon has now been accused of abusive behavior by at least eleven people of whom I am aware, including Ray Fisher, Gal Gadot, Charisma Carpenter, Michelle Trachtenberg, Amber Benson, Emma Caulfield, Sarah Michelle Gellar, James Marsters,
Buffy writer and S6-7 showrunner Marti Noxon,
Firefly writer Jose Molina, and
Buffy stunt double Sofia Crawford. Carpenter has noted that his abuse literally caused her to experience a medical illness due to chronic stress that she still suffers consequences from today, and that his firing of her after becoming pregnant was textbook illegal retaliation. Marsters has claimed Whedon shoved him against a wall because he was upset that his character had become popular with the fandom against Whedon's plans for the character at the time. Molina has noted that Whedon bragged about harassing a female writer into crying. Crawford has accused him of threatening to fire her and the stunt coordinator in retaliation for them dating. And Trachtenberg has alleged that there was a rule that Whedon was not allowed to be alone in a room with her (she was 16-17 at the time).
Singer, meanwhile, has been accused by multiple people of having sex with underage boys.
So let's get very, very clear here. These guys didn't get their names dragged through the mud. They dragged
themselves through the mud through their own terrible, abusive choices.
