This is a pretty old question but I just want to add my two cent as a muslim woman myself.
It's not rocket science, buddy.
What the hadith meant is that men should be more patient with interacting with women because we are different from them. More sensitive, generally.
It doesn't mean that men should not encourage women to be better. It's just the method is unlike the one you use for men. Men need to be up for a wiser, longer process, more sophisticated, more thoughtful, softer approach and careful with their words.
With men you can shout at them that they have messed up and no matter how they feel they would still able to think rationally (generally, or it used to be like that if not anymore) and correct themselves and talk to you the next day without even thinking about it's awkwardness. Regardless of whether it is the best way to deal with men or not, it still works better for men than women.
Women though, can't be handled like that. Even women need to be wise, understanding and soft with one another. Women are more self-conscious about how they look, how people will perceive them (generally). It has a good side to it, women are better at dressing themselves up for example. And men like to see beautiful things. That's just how the mechanism works. Like the mechanism of freezing, you can get delicious ice cream from it but you can get natural disaster from it too.
TL;DR it's explaining the nature of the creation of women and explaining to us how to go about it. Don't force the bent bone to straighten, you will break it. Though you can encourage it to straighten by itself little by little, with extra caution. And women who don't live life full of hurts would struggle less in accepting their role as mothers, would be less stressful, would be happier and therefore more generous. It's a good thing for their own life and for those around them. Because (again, generally) if men in the family breaks or absent the women would be able to stay strong for them. But when the women breaks, everyone else immediately breaks too. Or at least much easier to break. Much more stressful, more anxious, etc. For men, taking care of their women (mother, wife, daughter, sibling, etc.) is important, it's not easy and demand time and patience but trust Allah it will be rewarding. That's what the hadith is on about, it explains the reason, it warns us, it tells us what to do and that was what it is.
