This is a good point. Kinda wanted to say something similar but didn't want to look like I was playing devil's advocate. I have used bro for women and non-binary people, but if anyone doesn't want me to I won't. Same way I used to use chief a lot but some people thought it was appropriative, so I stopped.(not sure if it is, I've never heard a Native American person weigh in, but best to err on the side of caution.)
