I disagree. There is nothing wrong with 'bro' just like there is nothing wrong with a programming language 'Julia'. They are both gender specific and you as an individual can infer whatever you like about the term.
Only you, the individual, can determine how you feel about what someone says or writes, only you can determine whether or not you're insulted.
How something IS vs. how a group FEELS are separate, and one should not confuse the two.
Hm. I always assumed Julia referred to Gaston Julia.
Funnily I was working at a place where the HR manager was named "Julia Lang" so we all had a laugh when I discovered (and pitched) the language - with its website "julialang.org".
