Hey I'm a lefty too, and I object to paying premiums for "specially" manufactured products for lefthanders.
On the issue of shooting:
Having never handled a rifle before the army, it was quite easy for me to shoot it with the right hand, as I didn't learn it any other way, so no burn marks from ejected shell casings for me.
I think the notion that the left hand is the "bad" hand comes from the ambiguity of the latin word sinistrum, or rather it's change of meaning from left in latin to malign in English or German. Even today when somebody tries to take advantage of you, it's said "Er dreht eine Linke", "Linke" stands for a fraud in this case, if somebody behaves/moves "linkisch" he's clumsy or inept.
I'm just glad I wasn't born in a time where lefties were forced to do it the "right" way, with tying their left arm behind their backs.
LEFTIES UNITE!!!
