Hey, I like white bluesmen as much as the next (white) guy: Page, Peter Green, the guy from the Black Keys, Billy Gibbons, Jeff Beck, etc.; I was just saying (or trying to say) that Joe Bonamassa didn't quite make my personal cut. And I wasn't trying to offend, xmas -- my comment was meant to be more humorous than hurtful.
Also, I completely agree: blues is about emotion. To be more clear about my feelings on JB's music: it sounds way too polished -- like the emotion was scrubbed away. And that reminds me of later Clapton. All technical excellence, no grit.
