Right decision, we really do need to be making sure kids don't get foster parents with views that could in anyway compromise them. So we will need to stop placing kids with Catholic and CoE parents (their views on homosexuality are not really suitable these days) stop placing kids with Muslim parents (after all, that sort of sexist attitude needs to be curtailed) and certainly stop putting them with parents that run their own business or are upper level management (we all know how bad capitalism can be). If the parents vote Tory, UKIP, Lib Dem or Labour we should probably be wary too, the last thing we need to do is indoctrinate kids to support a particular political party.
Obviously we are going to need to massively increase the number of care homes and will probably have to reduce the number of adoptions for the same reasons too. But I am sure care is the best place for these kids rather than with a loving family that may have political views we don't like.
