I just want to point out that in the South, use of “sir” or “ma’am” does not imply age. It is simply polite. <snip> It’s habit. It’s civility.

Exactly. (Especially that part about it being habitual.)

But, then again, I love that men hold doors open for me, or walk between me and the road or offer to lift heavy items for me – I am something of a throwback.

Ma’am, can we talk?
Most of my female friends up North are Northern born and/or bred, and I can’t tell you how many times I’ve been told, “Li’l Pluck, sit down,” whenever I stand at the table for them to leave/approach, or how often I’m waved away whenever I maneuver myself to open the car door for them, etc., etc.
And the thing is, they KNOW that it’s not that I think less of women–I happen to be a very pro-feminist man–but I reckon that it’s just that they’re not used to this kind of treatment from guys up here. Or maybe they think they’re putting me out somehow. Or whatever, I don’t know, but it seems to freak them out.
On the other hand, my female–oops, lady–friends who are (a) older, and/or (b) have roots in the South/are themselves Southern really tend to appreciate this kind of treatment (I LOVE hearing, “Oh, Li’l Pluck, you treat me like a queen.”)* I mean, damn, it’s really no trouble for me at all.
(And, believe it or not, even those women who protest seem to have gotten used to me maneuvering to walk between them and the roadway. That’s progress, no?)
So, yeah, Litoris, bring the throwback on! 
*It occurs to me, of course, that were I a heterosexual man, I could…uh, well, you KNOW…**much ** more often than I do now.
