The risk isn't that someone gets all huffy and makes a big deal about being offended. It's that people who you would want to participate silently think to themselves "I don't want to deal with this" and then go away. It's explicitly not the oversensitive feminists I care about here; it's the reasonable, intelligent women and men who have a number of options on where to spend their time and choose not to spend it in communities where they feel unwelcome.
"Anyone who's offended by this isn't someone I want to spend time around anyway" can be a very effective way to filter your friends, but you have to be very careful that you apply it in a way that actually offends the right people. As an early-30s male in tech with a number of female friends and coworkers that I respect highly, I'll tell you that there are many people who my life has been quite enriched by who won't go near "brogrammer" culture or anything that sounds like it.
