Evidence isn't respectable?
People don't like Eminem for many reasons, it's not an attack on his "unmatchable" skills everyone worships.
Are 50 Cent, Nas and Jay-Z the only respectable rappers?
Shit, does that make Ja respectable too? That's retarded.
Canibus can only make diss records, sure. Eminem drops records brimmed high with fucking names. Is Mic Club a diss record? Gee, I don't see it that way. A much more consistent album than I've seen from Em.

Who really feels that he is THE BEST emcee? Please, no qualifying statements.
