See USA after Civil War, it wasn’t kumbaya, laws against the now free slaves were enacted (Jim Crow, segregation).
You're contradicting yourself here. I thought that most people were moral but here you're saying that enacting or abolishing a law doesn't make people moral(true!).
So the contradiction is that you're arguing that laws are a top-down imposition but here you're saying Jim Crow laws were bottom up.(imo this is historically innacurate)
I'll defer to Dinesh D'Souza on this one. It's a deep deep rabbit hole of rewritten, hidden and spun history. Start with the shock doc "Hillary's America"
Sorry! >_< I mean to say that you've indicated(I think?)that the NAP is independent of laws but then abolishing slavery(was that adding or removing a law?) didn't help to free anyone.
