WASHINGTON It was a yes-or-no question that shouldnt have been hard to answer: Is President Barack Obama a Christian?

Donald Trump has fueled speculation that Obama might be Muslim since 2011 , when he questioned whether the president was really born in Hawaii. Obama eventually released his birth certificate, but the GOP presidential nominee still refuses to disavow so-called birthers.

Still, the absurd conspiracy theory seemed to be an old story one that has been debunked so many times and that Obama himself has made fun of . But several people The Huffington Post asked Friday about Obamas faith at the annual Values Voter Summit, a conference for religious conservatives, showed that Trump has very much succeeded in raising questions about the presidents religion.

I do question it, I really do, said Linda Roller, referring to Obamas Christianity. One of the latest things I saw was even a symbol with his hand that was similar to a Muslim saying Allah is the only God.

Roller went on to say that she didnt think Obama was Christian because he didnt share her beliefs.

I mean just the fact that he is very liberal and the fact that he believes in abortion for instance, she said. And that he believes in a lot things that I dont believe in because I try to use the Bible as my guide.

Several people echoed Roller. Many believed that even though Obama said he was Christian, his actions, particularly support for pro-abortion rights and for Planned Parenthood , suggested otherwise.

He states he is, but we look at people by the fruit that they portray, Heidi Pezdek said. What Im looking at is his stand for abortion and support for Planned Parenthood, which is murder, murder in the womb, and his strong support of the LGBT lifestyle community.
