I have seen some of this stuff about Obama being a Muslim etc. on the net. This is from MSNBC. As usual the posts are not totally baseless but a mixture of fact and fiction. Obama's father was a Muslim and Obama was in Indonesia but rather than attending a Muslim school he went to Catholic and secular institutions.
"I've been to the same church _ the same Christian church _ for almost 20 years," Obama said, stressing the word Christian and drawing cheers from the faithful in reply. "I was sworn in with my hand on the family Bible. Whenever I'm in the United States Senate, I pledge allegiance to the flag of the United States of America. So if you get some silly e-mail ... send it back to whoever sent it and tell them this is all crazy. Educate."
