The question only really makes sense if all the white presenters were "talented". Who knows... but there is no real reason to suggest that "diversity" waters down "talent" somehow. I'm sure it's possible to have both.

No, aog... that hasn't always happened so far. Even if talents "shine through" they are still under-represented. Do you believe that "diversities" are actually less talented? Or do they get less opportunities? Which is it?
