One of the deeper issues that will probably never go away for many people in tech (no matter their gender) is the realization that completely fitting in is unlikely to ever happen, and that maybe this is a good thing. To pick up one of the metaphors used in the article: yes, if you're a squirrel, at first glance it may seem that all the other creatures in the forest are completely identical badgers - but upon further investigation it turns out they're all aliens from thousands of different planets, each wearing badly-made badger costumes [which, by the way, is also almost exactly the narrative of the original presentation - just watched it].
The issue isn't really the things, but in feigning interest in the things that don't interest you. You don't have to pretend to like something, but at the same time you can still find ways to share time with those that do. You cannot design an event which is all things to all people, the answer to being inclusionary is not to be dull, instead it's about inspiring people, and you might as well have some fun trying to do it.
Do I like cupcakes? Sure. Do women enjoy laser tag? They kick my butt plenty often. But it makes the workplace less accessible to people who don't like cupcakes or laser tag.
Really I wonder if we're just seeing that a workplace naturally has a culture, not everyone always fits in, and because in this case the divide roughly aligns with a protected class we are caught off-guard and concerned.
(Getting rid of culture in workplaces doesn't seem like a solution)
So it was cupcake tasting this week. You don't like cupcakes? That's fine. Next week it's yoga. Don't like yoga? That's fine. The week after that it's etc...
The way you want to paint it is that you have to like certain things to be 'one of us', the real message is that you can be different and still be 'one of us'. As I said before, you can't be all things to all people. The idea is to make things inclusionary by being fun, and I hope they continue, even if people want to make a point of being offended about eating cupcakes at a programming class.
There are games and activities that don't gender stamped all over them, yes. But cupcakes and yoga are pretty close to the activities which have some gender-attachments.
Male hackers rise up against those who would steal thy cupcake-loving birthright!
