These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Unfortunate Implications: Many. Nearly all the views expressed in the books, both original and modern, has the potential to offend someone. In both, there are misogynistic views.
Values Dissonance: There's a lot. To modern day readers of the original series, how her grandparents treat her as well as her father qualifies as Abusive Parents. Then, it was normal relations. There is also rampant racism towards the slaves, who are also portrayed as enjoying slavery and that it is good for them. Even when she hits her majority, Elsie does not control her fortune, letting her father and later Edward Travilla control her finances and her plantation. On top of this, many misogynistic views are expressed by both male and female characters.
