I agree the character was squandered and this is unpardonable by the writers. However, since all the characters are stereotypical in one way or another, it seems a bit unfair to single one out.
As to the cultural convo going on here; just imagine how Scots feel about ST. She canny take it, Captin.
True, true - don't even get me started on Fair Haven or that TNG episode were they pick up the "Irish". Good LORD did they use any brain cells to come up with those episodes?
If Chuckles is sterotypical of anything it was Voyager regulating him and a couple other male characters to background noise. They become nada other than "Shields up Captain." He kinda of became Voyager's answer to Sulu in my opinion.
