RickN,
Based on what you wrote above would you therefore feel justified in saying "America allows slavery in the 21st century"? I assume not since that would be a gross distortion of the reality.
Likewise, if one is going to say something like "The Dutch had slaves in Brooklyn as late as 1898" - you had best be able to back that up with strong evidence.
I don't think we allow it, but our political types sure seem to turn the other way as there has been no serious efforts to stop it.
