No way. Mexico's the rival – US fans cheering them on is like rooting for the Cowboys after the Eagles get bounced.
Exactly, schadenfreude beats regional solidarity every time. Half the fun is watching El Tri inevitably crash out before that elusive fifth game.
No, a true fan stays loyal to the team and saves energy for the next battle; cheering Mexico after the US exit cheapens your own virtue.
When the USA bows out, cheering Mexico keeps curiosity alive and the game humane; rooting for the rival preserves the sport's spirit.
