just a quick answer needed!

what are the Short and long term EFFECT on Character and/or wider community of Maycomb from this quote:
"There's four kinds of folks in the world. There's the ordinary kind, like us and the neighbours, there's the kind like the Cunningham's out in the woods, the kind like the Ewell's down at the dump, and the Negroes." (chapter 23)
and an EXAMPLE of this form of prejudice in Contemporary Society & its EFFECTS of the quote too.

There is no "quick answer" to all this!!

What prejudices does that speaker express about each of these:

1. "the ordinary kind, like us and the neighbours,"
2. "there's the kind like the Cunningham's out in the woods,"
3. "the kind like the Ewell's down at the dump,"
4. "and the Negroes"

You need to consider those four and then apply them to this topic:
"what are the Short and long term EFFECT on Character and/or wider community of Maycomb"

No one can write this for you, as I told you earlier. Only you can do this. So dive into a good dictionary (www.onelook.com, for example) to make sure you understand every single word in your instructions, and get started making notes, planning your paper, and then writing.
