Is it, though?
That's an honest question. I've taken that disdain for granted--even in my post a couple pages ago--but just realized that my only basis for this belief is TSR staffers who claimed that she disdained gamers, but offer no specific examples. But maybe there are accounts that I've missed.
The chain-mail-bikini rant might have been forward-thinking and feminist, or it might have been vicious slut-shaming. ...
There are a lot of accounts of her disliking the D&D customers. Too many to ignore. I've added another account from Mike Breault to me previous post with references. Note that in this account, she also calls another female employee a "stupid, useless cow" which doesn't help the image that Ms. Williams was a forward-thinking feminist.
I look at it this way. When you dig into people like HP Lovecraft, or John Lennon, or Gary Gygax, you'll find things you don't like. Lovecraft was racist, Lennon beat women, and we're hearing more stories about questionable things EGG said in his lifetime. It's important remember and know these negative details; we should not forget or forgive their misdeeds because of the things we like. But its also okay to enjoy the good things these people gave us, without feeling shame about their misdeeds.
We should treat Lorraine Williams the same way. If anyone wants to claim that Lorraine Williams was a positive influence on D&D, tell us about positive things she did. Find out what she did to pull the company out of bankruptcy when she came on board, and how her finance skill helped with debt management. Tell us about the deals she made to get D&D in stores, or increase the number or products released. Show us things we can celebrate.
But don't try and minimize the bad she did. Don't pretend she didn't have a vast amount of negative interactions with both customers and employees. Don't try and re-write history to make her business deals about Buck Rogers or the D&D movie rights any less scummy than they really are. You have to take the good with the bad, and no good will be done by trying to forget the bad.
