My point is not that women might like different things, just as Ted still enjoyed playing Weasel Escape, but that because of the T-shirts and all that they feel unwelcome. It's like the inside jokes making Ted feel left out. Sure they could explain the jokes and culture, and sure, there are probably lots of nice people in software willing to explain the culture, but it's tiring to feel like you're on the outside culturally even if the actual job (coding) is unrelated to the extraneous culture.
