being dual lingual myself I'd say giving instructions no one else understands could provide a huge advantage over the other team, it makes it an unfair playing field!

Have you ever been to a baseball game?

They use hand signals quite frequently to determine who will cover what base under what cirumstances, or which pitch to throw, or whether to attempt a pickoff, or any number of other "plays".

Those are not able to be translated by the other team, either. Should they also be outlawed?

Your statement is silly.

"Dual lingual" ? Would they happen to be English and Stupidity?

dual lingual?

Coaches regularly send "coded" hand signals to the base runners...no different than speaking a foreign language...infact, in this day, it's quite likely that some members of the other team also speak Spanish...
