What is the reason for mr obama to say "God Bless the USA" after his campaign speeches" when we all know he?

Obama says a lot of disingenuous things. We all know he attended a church for 20 years led by a pastor who is anti-American and anti-white. "Naw,naw,naw, not God bless America...God damn America". This is where Obama was spiritually fed for 20 years!
