He and Obama don’t talk about politics; Obama simply “goes out as a politician and says what he has to say as a politician.”
Wright sounds like he’s saying that Obama largely agrees with his worldview but hides his true feelings for political reasons, which might be true. But let’s interpret this more charitably: Obama disagrees with Wright but never discusses it with him. If someone who was “like an uncle” to you preached that the US government invented AIDS to kill black people, would you take him aside and tell him he’s off-base? You might, if you were remotely qualified as a political leader.
