Well I was using it as more of a 30 out of a 100 outliers.
I'm saying (and this is where the parallel breaks down a little) that if people want to have an epic nerf gun fight it should probably be scheduled, and out of the work place/time (like during launch, or after 5pm or something. And this is where it breaks down. Nerf gun fights are fine, but creating an environment that discriminates or (equivalently) encourages discrimination is never ok). They both distract many of the employees trying to work (i.e. the ones not involved in the discrimination/nerf gun fights), and it being able to break out randomly at any time is a massive continual distraction.
To continue the analogy. Consider an employee is doing their own thing to relax (as opposed to nerf gun fights), perhaps they aren’t quite a company culture fit (since they don't like nerf guns) and they choose to do some hoola hooping, but almost every time they go to do that, they get pelted with crossfire from nerf guns, making it difficult to do their own relaxing thing.
Now the other side (with the github environment with hola hooping women): Consider an employee is doing their own thing to relax (as opposed to hoola hooping), perhaps they aren’t quite a company culture fit (since they aren't interested in women. And for that matter, are a woman) and they choose to do some yoga, but almost every time they go to do that, a bunch of guys start gawking at them, making it difficult to do their own relaxing thing.
