Yay us! ;))))

Of course not! I've also heard that studies had shown that synaptic
connections between the two hemispheres were more numerous in left-handed
people's brains than in right-handed people's ones (thus making
communications between the two hemispheres more important than in
right-handed brains). In other words, brains of left-handed people would be
*less* lateralised than brains of right-handed people (which in my opinion
is compatible with what you are saying). So left-handedness is not
associated really with a swap of lateralisation but with a lessening of
said lateralisation.
