Re the Op, it is a little suspicious when any couple of one color adopt so many of another color, .
Only suspicious to those who focus entirely on race- like you- and Stevie- and Rosh.
To everyone else it is an inspirational story of two amazing parents with 5 kids of their own- who opened their house to foster kids, vowing never to break up a family.
But yeah- for people like you- all that matters is race.
