Now, we know that Barack Obama doesn't "keep" his actual brother — we remember George Hussein Onyango Obama, the brother who lives a hut — and it's clear that what he means is that government has the moral obligation to regard all citizens as brothers and sisters — I'm coining the word sibizens — and to care for them.
--Ann Althouse(commenting on a Greta Van Susteren interview of the President)
Update: at Just One Minute, Menlo Bob comments
Regarding Obama's comment about being your brother's keeper; He seems positively engaged in carrying out what he calls God's commandments--even though on closer inspection (Genesis 4:9) the source of the 'brother's keeper' command is derived from Cain responding to God's inquiry about his brother Abel whom he had killed. In other words Obama has confused God with a murderer.
Happens all the time.
