How is he an idolater for saying Obama is trying to put himself above God?
Whether Obama is trying to do that is another issue entirely. I just don't see how saying that would be idolatry.
Moment is an idolater for saying that the US flag is God.
Someone (not even Obama himself -- probably some marketing person who may or may not be working in an official capacity for the Obama campaign) put Obama's "O" symbol on an American flag, replacing the field of stars. Now, this could be seen as anti-patriotic, even desecrating the flag. I could see that this could be seen as anti-American, even. But the flag has nothing to do with God, so how can Moment see this picture somehow as Obama trying to put himself above God? The only way for him to invoke God into this picture is for him to imply that the flag is somehow representative of God. THAT is idolatry.
Now, whether Obama is anti-American is certainly debatable. I could understand arguments on both sides of that issue.
Whether Obama is Christian could be argued, as well. But a picture of an American flag is not going to figure into that argument.
