The more time goes on and the more experience I get the more cemented this becomes. The best example is the expression you guys. Nowadays that expression is fully gender-neutral and is routinely used to refer to a group of mixed gender individuals. Some people can feel excluded by the term, and for that reason I do often try to substitute a different term for it, but many of the women I work with use the same expression of you guys even when referring to a group of entirely women. I strongly wish that most people would hear that and not think of a gendered reference. I think that would radically improve communication.
If there is doubt about what the person meant, sometimes a clarifying question can be extremely useful. For people that are trying to use offensive or exclusive terms, it is good to push them on that a bit and ask for clarification and such. But I don't think I've met anyone who was using the term that way in many, many years.
