the problem is not with what you are thinking when you read the word "bro", but with what other people, especially newcomers, are thinking.
And anyway, how far should we take that? It is really difficult for me to conceive that many people would find this meaning in it. If I find out the name of my project is offensive to 50% of my audience, should I change it? What about 25%? 10%? 1%? One person?
