Obama states his religion is: United Church of Christ. (that doesn't make alot of sense - but here is a little about Obama's UCC)
UCC supports abortion and homosexuality.
In fact in April UCC is hosting a 'Called out for Good' conference for ordained ministers and other clergy . There are many other LGBT conferences.
They are Against the Patriot Act
It makes a lot of sense if Obama is not really a Christian, but thinks it good for his career to have some people THINK he is a Christian. Personally, I think he's a Muslim clothing himself the the pelt of the Lamb
