When I was growing up we had one car in my father's name. So strictly speaking only 25% of the family owned a car but 100% drew benefit from it.
Likewise with slavery. Only 15% of Georgians may have owned slaves but add their wives to the equation and about 30% of the population benefited from those slaves. Add children and possibly half the people directly benefited from slavery.
They were fighting for states rights and to repel an invading military force.
State's right to do what?
Lincoln didnt give a rats azz about slavery until the war was not going well...
Debatable, but one cannot deny that the South certainly gave a rat's azz about slavery from day one.
The United States Census for 1860 put the percentage of slave-holding families for Georgia at 37%
