Ma'am is a regional and cultural thing. I don't know ANY woman my age I grew up with who likes it - well, maybe a friend who is a Colonel in the Air Force, but that is military. It's not an alternate universe and please show me an instance of anyone calling you a "Bitch" and I will look into it.
Not an acronym, a "Bitch"
Ma'am to me is offensive and I am not alone. WALDT...you don't find it offensive, I do. That does not mean you meant to insult me...
But many women see it as an unnecessary salutation meant to remind a lady that she is older and no longer a "Miss" - it's usually an unconscious bias (which happens to be a major part of my academic field of study). It
might be a sign of respect. Or it might be a reminder to older unmarried women that they are...older and unmarried and that is against the norm. Ma'am implies a married woman. I am not. Ma'am implies an older lady...I may be older, but is it nice to be reminded of it for no reason???

On top of everything...Ma'am is a contraction for...wait for it...
MADAM!!!
And I will call absolute BS on anyone over the age of 21 who doesn't know that many women think Ma'am is offensive.
I've made it known...I don't like Ma'am or Madam.
