Just like your Chinese ascendants would have said when building the big wall.
You are referring to my ancestors who built the Great Wall. Yes, that was the mentality of my ancestors
20 centuries ago.
Now let's have a look at Chinese history.
The integration of China with the rest of the world developed over the centuries - the Silk Road leading to Europe was built to facilitate integration, trade and commerce. Many foreigners (the most famous, Marco Polo) came to China, and commercial and cultural integration was prevalent. As a result, China was the most powerful country in the world for many centuries until 250 years ago.
Because of its wealth and power, many Chinese started to call foreigners "barbarians", and the government (Qing Dynasty) decided that it should close its doors to "inferior people" to prevent them from perverting Chinese culture. So the Chinese lived behind closed doors when the rest of the world advanced. The decline of China did not take long - 200 years later, China became one of the poorest countries in the world.
30 years ago, things took a turn. China opened its doors to the world once again. Since then, trillions of dollars of foreigne investment has been injected into the Chinese economy. And as the wealth accrued, China also became part of the international community to invest in foreigne countries such as Poland, generating jobs and boosting the economy there. Many Chinese left China to live abroad, and more and more foreigners chose to come to live in China (yes, including Poles). Children of foreign migrants started to appear in Chinese national teams in the Olympics. The result of integration? China has been the fastest growing economy in the world for the past 30 years, and it looks like China is on course to become the world's most powerful country once again.
The rise, decline, and rise of China, the contrast is striking.
I belong to the "yellow" race (East Asian). You belong to the "white" race (European). Are you inferior to me? Am I inferior to you?
Those who are truly inferior are people like z_darius (and SamenessLove, if it is not the same voice), racists, white supremacists, and Nazis. This is regardless of your race, despite the fact that you have a sheen of "superior" white skin to cover up what is inside - hatred towards fellow human beings.
What you promote is to downgrade human beings into the most primative zoological species. It is against the most basic human decency, against civilisation.
