Britain's Flourishing Slave Trade

So you thought the slave trade went out in the early 19th century? And slavery itself in the American Civil War.

Of course, this new slave trade is not supplying strapping field hands for the cotton fields. It is supplying girls for the sex trade. Is that what liberals mean by “sexual activity”?
