No one is saying that modern slavery doesn't happen or that it isn't something that we should be addressing. I'm taking issue with the specific language that one person used earlier: "There are more slaves in the west today than at any time in human history." So far nothing that's been posted corroborates the notion that there are currently more slaves IN THE WEST than at ANY POINT IN HUMAN HISTORY. Posting links about slaves in Africa, the Middle East and Asia doesn't address the portion of the claim that is specific to the West. The site specific to the US that was linked says they've handled ~23,000 cases, which is tragic in this day and age,
You must keep in mind that's one organization handling 23,000 in four years. There are many more organizations that have operated for longer; It's safe to assume that they total much more than 23,000 cases.
but not even remotely comparable to the ~5 million slaves in the USA around the time of the Civil War. So it seems like it's bullshit hyperbole to make the claim that there are more slaves in the West today than at any point in human history, and I don't think bullshit hyperbole is really helpful when it comes to addressing a serious crisis like this. Why should there need to be more slaves than at any point in human history for us to care? 23,000 is shocking enough on its own, let alone the millions in Africa and the East. Turning to hyperbole weakens the argument because it allows people the opportunity to dismiss it as bullshit.
There were around 3.5 million slaves around the time of the civil war:

Again, I'm not certain that you can claim it's bullshit hyperbole. Haiti alone, just counting the child slaves that operate mostly inside a house, number 225,000 at the minimum. Never mind all the other child slaves.

What we need, is a source compiling all the statistics from USA-based organizations, that combat human (sex) trafficking, slavery and the like, and then produce estimates of all victims that weren't rescued.
I'll agree that his statement was not explicitly backed by evidence explicitly, but you shouldn't go declaring that the number is far fewer; rejecting the claim is valid, responding to it with a claim without a source, however, is not valid.
Agh. It's hard to gather statistics on this issue. You'd think the World Health Organization would have, at least, compiled estimate figures.
On a somewhat different note, this was a good read. Not relevant to this discussion, but good to know.
