If in some parallel universe all programmers cared about indie music, craft beer, Pinterest, and potty training woes, I might not want anything to change. But if marginalized people said they felt excluded because they don't looooove glitter, I hope I would be decent enough to shut up about craft projects for five seconds and try to find common ground.
My region's annual linux convention has a list of craft beers that will be available that's much longer than the list of events. I made a point of not saying that we shouldn't alter our behavior to be more inclusive, just that I'd be sad if the only common ground we could assume is knowing how to write software. It'd be a small price to pay for progress, maybe, but it would be a price I would regret paying.
