Help! pt-br translations in pt

First of all, I'm not a vandal, as this user above tries to say. As I don't intend to make this a war, some words are very similar (only one letter different), these ones I agree to revert, but this represent only a few messages. The real problem comes now:

Let's make some things clear:
* There are two main countries that speak Portuguese: Brazil and Portugal. According to http://stats.wikimedia.org/wikimedia/squids/SquidReportPageViewsPerCountryOverview.htm Brazil has 3% of page views in wikipedia and Portugal has 0.4%. That's a big difference, but in fact, the pt version, is an european portuguese version, because most of messages were translated by portuguese editors. What I wanna do is changing some words to brazilian version, because we are much more users.
* In the past, there was a "pt-pt" (european portuguese) version, but was removed due to lack of translations
* Some users (not brazilians) translated a lot of messages in pt-br, and I had to correct some. If you want to block someone, block these editors who translated a version they don't speak.
* I remember the namespace "User" was "Usuário" and somebody changed to "Utilizador", and I didn't see this user complaining about it.
