I myself appreciate MLs style ! He reminds me of my grandfather who was "brusque" yet adored by all and also the better teachers in my life who had a style of speach similar to MLs, but when they spoke you listened because you knew they had something to offer!
I believe it is we who have been conditioned to not except any variation in the species, who demand that all act according to Hoyle!
If we all talked and acted the same it would be a pretty boring world ! I think it is MLs attackers who are thin skinned with oversensitive egos that are ignorant!
