Its not, i am black and i am pissed at the way they treated their black population research it they basically got them extinct their fans are one of the most notoriously racists fans they were insulting the french players of african heritage the Argentinian fans
But what does any of this have to do with the players on the team? Most of them don't even live in Argentina and live in multicultural countries with black teammates.
Furthermore , a foreign black person could make the same argument about America. Imagine the US squad winning and Jamaicans, Congolese, and black Britts say fck America for lynchings, trail of tears, imperialism, etc.
