Lol... How do you know that many barzilians are liberal, Chase??? How?
I am not sure about that...I know a lot of conservative people ...I think we have a image of a liberal country, but isnt the true. And polemic issues like abortion and gay marriage, for example are not allowed here. Maybe being the biggest Catholic nation is the reason of that.
Just an historic note: Portugal was the first State to appear in the (Spain was the second) Modern Age, so portuguese had a lot of points that gave resulted in the pioneer position concerning to the expansionism in sec XV.They had technology, capital,and the religious support. So while Britain, France and Netherlands were involved in disputes, and having also interior problems to solve , the iberians got ahead of the expansionist process. And after that, everything that Portugal needed to do was to impose a strict colonization model: which means exploitation and the consequence of that of course you know...
