Great. Thanks for your answers. I got back to the officials who were in the game and asked them why they opted for the ejection.
They asked me to give you the context, to see if that would change your opinion on the ejection, or if, for you, it's always the same:
1- Brazilian players are not disciplined, the "soccer culture" of flopping and fighting for nothing has spread to almost all other sports.
2- They thought that they had to make a statement, otherwise the other team would retaliate hard, because they have a history of doing that.
3- Our players aren't as technical as American players, who are born with the football in their hands. They try to take up a game frequently by intimidating and using this kind of behavior to get into the opponents' minds, so they thought it'd be best to nip it in the bud.
Even though they were in the finals, that doesn't mean they are technically good. If you watch the game, you'll see some good plays here and there, the best of them from Cody, the American guy in black. We are improving, but soccer culture of flopping and fighting is too infectious, so we're trying to educate the players to become athletes, and that's why they opted for the ejection.
I thank you all for your inputs, it helps a lot, and I'm more of a lurker, but your opinion is really important to us.
