Personally I think that every instance of couples abusing their foster kids is a tragedy. The homophobes only pretend to care when it involves gays. There is a serious problem with foster parents abusing their wards in America- and despite the best efforts of the homphobic bigots- it isn't just the gays doing the abusing.
Children removed from Roy home after foster parents booked for felony child abuse
Police said the parents had tied three boys between the ages of 7 and 11 to the bed using zip-ties. The parents would lock them in a bedroom and would not allow them water after 2 p.m. At one point they allegedly duct-taped the children’s mouths and hands.
The parents allegedly locked the boys in their room, which had no light bulb. The window was painted black and screwed shut, police said.
Police say the children had no bedding and were wearing diapers. The parents also allegedly disciplined the boys by forcing them to eat rice that had too much salt and cayenne pepper added.
