It's only the same thing if they don't know anything about the Triple A Atlanta Crackers and Negro League Atlanta Black Crackers baseball teams named as such for the whip cracking muleskinners who loaded and offloaded trains in Terminus/Marthisville/Atlanta at the siuthern end of the Appalachians. Not to mention the Scots crackers who were called such from their expression “Let's have a wee crac” Meaning a bull session with jokes cracked. And fittingly for this story, there is a hardy breed of small horses called Florida Crackers. Call me a cracker anytime, I grew up watching the Crackers play in Ponce de Leon Park in Atlanta.
I was taught, in a Georgia public school, that the term "cracker" simply referred to someone from Georgia.
The minor league baseball team in Atlata (prior to the Braves moving there in 1964) was call the Atlanta Crackers.
The negro league baseball team in Atlanta was also called the Atlanta Crackers.
This is a reproduction of a 1939 Atlanta Crakcers baseball jersey:

In fact, you can buy Atlanta Crackers uniforms (both the minor league and negro league versions) all over the internet.
Cracker is about as much a slur as calling someone from NY a yankee. Yea, when someone from the south says yankee, they mean it negativly, but few people born up north would take it as an insult.
When people up north say cracker, they mean it as an insult, but few people form the south take it that way.
