I don't want to be offensive to people either but I also don't want to have to keep up on polling of what the plurality of any particular group is okay being referred to as. There are an infinite set of groups that I'd have to keep track of.

I'll find out if something's offensive when I say it, with no ill intent, and someone respectfully lets me know that they'd prefer to be called something else. My language will change over time in response to the overall language changing over time.
