Sort of off topic. But if you are putting a disclaimer that something is "gender neutral", just use a different word. Y'all? Fam? 😂
For those that say these are inherently gender neutral, how many bros have you slept with? Would you sleep with a man? This is all literally patriarchy. Male isn't the "default" human experience.
Firstly, does thinking a "(gender neutral)" at the end of sentance is really weird and awkward truly make me the language police? Come on, it's clunky at best, a weird lazy lamshapde to virtue signal at worst. Just use something else if your intent is to have something gender neutral.
But to answer your question. If your lady friends don't mind being called dude, then why should I?
Your argument doesn't really work, because 'bro' isn't a word used to describe sex partners, in the same vein, you would never say "I've slept with the boys", but you could use the sentence "I was hanging out with the boys".
Sure, I'm not really trying to play a semantics game so much as call attention to the fact that these are inherently gendered terms. If you were to say "hanging out with the girls (gender neutral)" or say "hanging out with the boys (gender neutral)", you are just being awkward and should just change the word.
That's fair I suppose, to me, "bro" is an inherently gender neutral term, though "girls" is gender neutral to me in the same vein.
Adding on the 'gender neutral' is kinda redundant, and I can see why it would be annoying, actually, it's annoying me too now, because if the writer simply used "bros" and not "bros (gender neutral)", the expression's gender (gender/non-gendered) would not have been moved to gendered, and most people would understand it to be a gender neutral expression.
I had a straight non-binary friend once; ze was small and androgynous and ze would generally date "lumberjack witch" enbies or other people who were differently gendered from zir.
