From Jerry Pournelle "migration without assimilation is invasion"
We have made the idea of assimilation a bad thing in popular culture - it is too....BORG like. Except, the 'melting pot' is an important part of becoming American. If you leave your country, go to another country (ANY other country) you will be expected to learn the language, follow the laws and participate in their culture. That is how my parents were expected to act when they came to THIS country, and how they planned to act. Now, we not only don't expect them to follow our laws, we are going to bend our culture/society to their expectations!
The 'anti-appropriation movement' is a direct attack on the 'melting pot' assimilation process.
The first step in assimilation, in becoming American, is to lose the hyphen.
