This is terrible. It is obvious that many of these children will not have been associating with other children that might grow up to be gay. So, there is absolutely no reason to kill them.
This barbaric and sickening practice will be supported, in part, by exactly the same people that the Ugandan minister of ethics cites when he says it's okay to oppress and kill gay people because that's what people in Uganda want.
No wonder the Ugandan church and state authorities don't want the West meddling in their cultural affairs.
