It’s not out of context. The surrounding material shows clearly that Obama was criticizing his classmate for not being “Black” enough.
I’ll take your word for it. However, more text would be needed to convince skeptics, for example, a mixed race couple who were intending to vote for Obama.
I went to the bookstore and looked at the book, without buying it. I read pages 101 and 102, to confirm/disconfirm your claim.
I could not confirm in these two pages. On page 101 Barack Hussein Obama (BHO) describes his hero who he considers to be more authentically black than himself. The quote you provide is right for the time. The young BHO does reject Tim, the supposedly white acting black man who has a white girlfriend, for not being sufficiently black. His hero chastises BHO. His hero asks why did he disparage Tim. BHO dissembles with “he’s just goofy.” Yes, the young BHO was a racist who wouldn’t even tell the truth about his racism. But the modern BHO, with his unacknowledged ghost writer, shows the young BHO as having been rebuked by his hero. His racism was wrong.
BHO may still be a racist, but these two pages (101 & 102) do not prove it.
