Thank you for stating this. I've come to know a lot of Hmong through my church, and let me assure you, the ones I know are as horrified and sickened by this as everyone else is.
Or as my wife puts it, as mortified as her Italian immigrant grandfather was by the crimes committed by other Italian immigrants during Prohibition.
My great grandfathers father changed the family name when he came to America immediately before WWI to make it appear less German.
