The people who make the television show Gotta Grudge, and the people who watch it, should be ashamed of themselves.
Meanwhile, why are the police not looking into this? In Canada, dueling is illegal, and punishable as an indictable offence under s. 71 of the Criminal Code.
(a) challenges or attempts by any means to provoke another person to fight a duel,(b) attempts to provoke a person to challenge another person to fight a duel, or(c) accepts a challenge to fight a duel,is guilty of an indictable offence and liable to imprisonment for a term not exceeding two years.
I believe that a very strong case can be made that this is exactly what Gotta Grudge is doing. In our society, we allow a certain amount of organized violence, within the confines of licensed and regulated sports. We do not allow private citizens to settle their "grudges" through violence, or at least I didn't think that we did.
It seems that I was wrong.
