The big difference between characters like Lori and Daryl is the fact that one of them remains a very polarizing, one dimensional character while the other has shown a decent amount of character growth and turned into a genuinely interesting character. The same with pretty much the rest of the cast of characters. Most of the characters on the Walking Dead have shown some type of character development while started out with a holier than
thou Queen Bee mentality and hasn't really deviated from that. She has shown no growth, no development. She is simply an unrepentant bitch.
Going back to the conversation between Lori and Andrea, you may be right, maybe Lori was resentful of the fact that she is in the house all day cooking and cleaning while Andrea gets to carry around a gun, hang out outdoors, and watch for zombies. However, why is it Andrea's responsibility to be in the house with the women? Why is it that a zombie apocalypse happens and suddenly everybody is forced back into a stereotypical gender role? Why didn't Queen Bee Lori go to Glen and tell him to help in the kitchen while she runs into town to get her own things from the pharmacy? Why didn't she ask Rick to watch Carl while she checked the perimeter. Never saw her telling T-Dog to do the laundry while she...well that's not a good example because we really don't have any idea what T-Dog was up too. The point is, there were several people living on that farm all season long and at any point in time Lori could have asked any of them to help out with the housework. Instead, we get a scene where she yells at Andrea for not doing her share of the women's work.
That's kind of silly. Lori has been anything but one dimensional. And she has also been anything but unrepentant. You can dislike her all you want, but those are not really traits the character possesses.
She has been torn for the better part of 2 seasons over the role SHane plays in the group, her guilt for being with him, the idea that he may be the biological father of her child, and his usefelness to the group. There's also the part where he's a possessive, crazy loon who tried to rape her. People just chalk it up to her being inconsistent, but it's all there, the struggle for the character.
Same with wanting (or not wanting) her children to live in that world. Despite the struggle, she has consistently come to the same decision, life.
And as far as roles, she has accepted her role with regards to the group. SHe doesn't claim that she is as capable as Rick or Glen in providing for them. But there is the fact that there were 4 women doing pretty much all the cooking and cleaning on the farm. Why do people HAVE to revert to those stereotypes? They don't, but even in the comics it's pretty established that those were the dynamics of the group.
I don't have to agree with Lori about Andrea's role to understand that the dynamic presented is realistic and would totally happen. Up until that point, Andrea's huge contribution was sitting on top of the RV and almost killing Daryl. Oh, and her suicide attempt. Oh, and being a bitch (which Lori called her out on in the woods and Andrea totally backed down from).
