I don't think human traffickers care. I don't think they would treat other migrants they are scamming for money any different.
Anyone who could cold bloodedly murder innocent people doesn't deserve to be excused because folks "hate Palestinians". Blaming the Palestinians for this is really low.
That little girl certainly did not deserve to die like that.
True, they weren't Palestinians, just bodies. Slavery's alive and prospering around the world, even right here in the US. Until we decide to end it it will continue. But because we function on a capitalist system, if cheap labor or slave labor is available, some will opt for that option to be competetive. So long as US companies outsource to cheap labor markets which sometimes use slaves, demand for slaves will remain.
Apple's a good example of our hypocrisy. American company, arguably one that's integral to our lifestyle, yet they build the iPods in facotories with such horrific conditions they literally had to place a net around the building to catch workers trying to commit suicide leaping out windows.
Reason human trafficking goes on is we enjoy the fruits of slave labor. If it comes down to paying substantially more for our goods by eliminating slavery, or paying less by turning a blind eye to it, we turn a blind eye. Sad but true.
