Not necessarily. There are many good aspects to Brazil. Brazil is still a Latin American Country. Not really multicultural is the sense that you use. They wanted to get rid of the black population by encouraging Italians and Germans to move there, and their influence is felt. Stan Getz helped popularize Bossa Nova. And let's not forget the Japanese influence---without them, the world will not have heard of BJJ.
remember they were a part of BRICK, and was making waves with its Energy Independence

Whereas, yes what you say cannot be denied, that they have a ton of poverty, violence, crime rates are up, and it will probably get worse due to the bad decision to host both the World Cup and the Olympics back to back.
Yet, Men from all over the world will still flock to Brazil for its sex tourism. Odd huh?
Now, I think what many people mean about multiculturalism is that people don't intergrate into the country's society that they immigrated to. Meaning that said people refuse to adopt the host country's culture, language and customs and resolutely keep their own. And Western nations instead of being a potpourri of cultures with a unified national identity, they have become a "salad", with no uniform identity. As I am aware, Brazilians, speak Brazilian Portuguese, whether they are German, Japanese (Brazil having the largest Japanese population outside of Japan), or Italian, or other. Sure, many still retain some cultural/ethnic practices, but they consider themselves "Brazilian".
How is that even a talking point or consideration? We're talking about far larger things than trivial hobbies. This is so much bigger than some fringe sport that few people care about.
Let's get to the bottom of this; the important points that matter, not the small stuff.
Ask yourself this, is Brazil a country that you would want to live in? Do you identify with it's culture, what its national heritage stands for? I'm not asking if you agree with or support these things, I'm asking if you identify on an individual basis with this country (brazil being just an example, insert any country in it's place) Would you want to live in a country that is known for the things that it is known for?
I'll go further.
Would you willingly live in an area that is multi ethnic, if you also had an option to live in a mono ethnic area consistent with your own ethnicity and heritage of upbringing? I certainly would pick the mono ethnic society without a doubt or hesitation. I'd be willing to bet you would too, as most (Liberal SJW idiots don't count, they are brainwashed) that I have asked this question to also provide answers consistent with my own. That about sums up my point.
This silly experiment needs to end, people want to live with and be around other people with whom they identify and have things in common. I've met a lot of different cultured people in my life, and no doubt will meet many more, yet all of my friends are white, all of my family are white, and all the women I've been interested in emotionally have been white. I've looked at my family members' friends and people that they surround themselves with- again, all white. This wasn't by accident, but it wasn't intentional either. I simply cannot identify enough with other cultures to accept them willingly into my world. It's not that I don't want to or that I have anything against them, it's that it feels completely unnatural to do so and to do so would be forcing something not meant to happen.
I've had friendly relations with black and middle eastern people, even the odd jew, but I am not friends with any of them. My last place of work was 60% indian, 20% filipino and the rest white; these people automatically sorted themselves into groups when it was lunch time, based on ethnicity. There was no animosity, just a mutual understanding that we all wanted to be with our own kind. This is why I do not believe whatsoever in an interracial society; in best cases it is awkward, in the worst it is violent, chaotic and degenerate. See Europe for excellent proof of that.
Bringing 3rd worlders to our 1st world nations is a terrible injustice, as the terrible places these people came from originally are a result of the populace itself. The more of these people that come, the more the host nation will become like those it is hosting. This is an injustice to those already living here. The govt should be held accountable for not looking after it's own people by the action of welcoming those who would undermine and degrade their existing way of life. This is the complete opposite of even the bogus concept of modern democracy(see my previous posts) where majority rules, as now the minority are favored over the majority and receive preferential treatment and benefits based upon their ethnicity.
It's not a question of language either, or even minor physical differences (can you tell a Pakistani from an Indian? These two peoples have had terrible relations historically speaking and look very similar), it is a matter of genetics and of race. Of blood. This isn't politically correct of course, it isn't a 'kind' truth, but it is the truth and the sooner people begin to understand it the sooner we can ALL be happier and better off.
