Seth MacFarlane doesn't write the **BOO** show himself - there's a whole writing staff, and as I hear it's a pretty democratic process so if Seth wanted to inject his "liberal atheism", the other writers went along with it so they should be held accountable too.
Besides, your argument earlier about little kids watching it - there are a billion things wrong with a kid watching this show, and saying there's no God doesn't even make the list.
Uh..........wa......uh......you......you think of something.
