"The point dumdum, was that Lawrence sees women as either submitters or bolters, and Gudrun was clearly the bolter, not the submitter."
That is NOT how Lawrence sees women; you once again oversimplify.
That's not how he views the mother in "The Rocking Horse Winner."
Connie isn't "a bolter," she stays true to her husband until both he's too much of a prick and she decides of her own volition it's time to move on and create LIFE...she isn't fickle at all.
Nor is Gudrun or Usula.
That's not how he views Gertrude Morel, who is repeatedly abused by her husband, which Lawrence both condemns and has the guy admit to himself he's been a prick over before HE dies in "Sons and Lovers"...
And then you have Paul, who's a dick to Miriam (who's quiet and passive) and ruins things first with her, and then doesn't have things work out with Clara (a feminist) and so Paul goes back to his mom, and when she dies, is left alone to realize what a fool he's been.
Lawrence gives a full range of different women, and in case you weren't keeping track:
Sexually-liberated women, like Connie, Ursula (to an extent) and Clara fare FAR better than women who submit, the way Miriam and Gertrude do, meet worse ends.
I'm sorry that you seem to have a huge problem with sexual liberation, but that was a big deal in 1920, and remains one today...and that's an area where Lawrence consistently has liberated heroines turn out better than non-liberated ones, but no, of course he prefers "submissives" only...
Why, he's just GLORIFYING the ultimate submissive, Clifford Chatterley's elderly caretaker, isn't he? Isn't the sex-happy Lawrence positively gleeful at the disgusting display there between that simpering submissive caretaker and a man who is impotent, chauvinistic, and increasingly-cruel to everyone he meets?
"Far from demonized, Gerald is the object of DH Lawrence's mouthpiece's affection. That's how he ends the book for crying out loud."
Yes, he ends the boom by lamenting the BAD END that affection came to...that gee, maybe being an uber-masculine abusive prick who in the end stifles rather than encourages sexual liberation is a BAD thing.
Birkin is far more his mouthpiece--he ends the story with his words, he represents the balance Lawrence seeks between the genders, and not only encourages sexual liberation, but brings it to a whole new level when Lawrence dares explore homoerotic-ness in the book, something Birkin is far more open to than Gerald, despite both participating.
And again, contrast the ends of "Chatterley" and "Women in Love"--
The latter features a frozen, stiff, dead Gerald, whereas the former features a final reference to fiery-hot passion ("fucked a flame into being") that features more than a passing reference to something ELSE stiff in the human anatomy, but where Gerald represents death and the failure of not realizing the Lawrencian ideal, Connie and Mellors together DO represent that ideals fulfillment...
A flame, passion, heat, and, in an earlier scene where a parallel is drawn between their intimacy and a newborn baby, LIFE.
Lawrence ultimately celebrates life, sex, and (gonna say it again) sexual liberation, which is the result of those two things, and NOT the result of types like Gerald or Clifford, hence why they meet bad ends.
