I think the surprise is just the fact that she has Haitian adopted children.
It opens many strands of thought:
Is she comped by the Haitian adoption trade?
Is she a true good heart saving these kids? How does she know of the horrors then if she is genuine?
Is she being used to bring Haiti to light?
The Reddit itself isn't much interest, the pic with her kids is.
Maybe it's the beginning of their smear attempts on her?
"She's a racial carpetbagger"
