Snopes has an article on some of these quotes. Of course they try to debunk them. In the process, I learned that while some of the quotes were edited or taken out of context, that they still carried much of the meaning and intent of the quotes from the emails. Snopes had, in some cases, added lengthy explanations explaining very subtle context differences to make the email quotes seem more out of line than they actually were. I left my brief research with the feeling that Obama has not said these things on a Tuesday, but on Wednesday, and that was why Obama is still as pure as wind driven snow.
I read some of the above link that tried to debunk these quotes. Seems to be a ‘that’s what he said but not what he meant’ mentality.
