I don't see anything in that interview where she says she hates this country though.
It's that bit about "the country that enslaved her" (the writer is responsible for that - but it seems to precede her remarks on the topic), then saying she can't be patriotic because of all those things...it offended a lot of people.
As far as I know, Alicia Keys is not currently, nor has she ever been, "enslaved". It just annoyed me.
