Will Obama's Decision Silence Critics? (Probably, but there are still questions)

Well Obama finally quit the church he attended for over twenty years, but is he just trying to cut ties with a controversy that nags at him like a tiny dog nipping at his heals?  The below article from McClatchy Newspaper highlights a few points I think are worth discussing. 

1. Obama is quoted as saying "... the racial and other controversies of recent months had become too great a distraction.."   So he didn't find the racially charged comments and other controversies spouted by Write a distraction the last twenty years before he was running for President?  Now that Americans know how his spiritual adviser for 20 years feels about America and whites, he finds the comments a "distraction".  
2. The article goes on to say that the polls show Obama needs to work harder on building trust in working-class white voters. So quiting his church now, after 20 years and not denouncing their anti-white or anti-American views is going to build that trust?  This sounds like regular Washington Politics to me.  Tell Americans what they want to hear and lie about how you truly feel.  Even Rev. Write saw through Obama's deception and he has known him for over 20 years.  That should speak volumes to Americans.
3. Obama said he didn't need to respond to everything that the church preaches.  I think it would have been more believable if he would have done all this before he started running for President.  This just makes him look like another Washington politician spouting the usual BS.
