Words are very important, I’m sure we’ve all heard a stirring speech or debate that made us feel strongly, is it so ridiculous to think that words like this could also make some communities feel strongly?
(I've also had women say, they'd never become programmers - its to competitive and macho), to be more inclusive language means something to many people. I'd feel silly for example if instead of saying fork a process, we say we nurture a child process. I can't speak to race - grumpy old white guy, but I can see how it would matter.
Once critical mass is reached (enough girls where they don’t feel like outsiders) the machismo calms down. Not once have I ever heard a girl in class say anything about the language. It’s always been about the behavior of the boys.
