Is "whiter than white" a racist phrase?

.....cause i got slammed for it and was shocked. i didnt even see the racism in it.....made me think that maybe people who did were thinking about it too much?

what do you think?
Update: pls give examples of racist context....
Update 2: i meant it in the sense of too good to be true....i was even refering to politicians....but everyone took on some warped view of obama and whatever had nothing to do with it....i could believe people dont have this phrase
Update 3: ....but even with the racist view....i cant think of a sentence or context where i could use the words in a racist way....
