Difficult. Some thoughts
I never saw it as an issue until it was fairly roughly pointed out me in the 70s by someone in Women's Voice. I did enjoy it later when she asked where the "Ladies" was. I pointed and said female toilets are over there.
Since then, I've tried to avoid it.
But...
Hard to see why calling a woman a lass is patronising, when I'd quite happily call a man lad. But then I'm a Northern boy. [See?]
Referring to groups? Probably say, "OK, guys, in this release we'll..." whether it's men/women/mixed.
You don't want girls? Fine, but don't ask for ladies.
"Would you say the right boy?" Yep, as in "Can I have a big strong boy over here..." when the team's average age is 30s [excluding me]. Most likely to say girls only in the phrase "Boys and girls" because they're all so damn young...
Politely addressing people? Sir or Ma'am, used to be for folk older than me, now as I'm older than Methuselah anyone who I'm in a service relationship with.
I quite dislike being first-named by people who are serving me in shops, or health professionals. I think I should be Mr'd, or Sir'd. I'd not call someone by first name on first meeting but that's very old fashioned.
People I'm close/affectionate to/with are quite likely to get surnamed, as in "Hey, Chap. Coming for a swift half?"
I suspect we shouldn't do it, but there are other issues I'd rather focus on...
