I continue to believe that you are confusing terms. An education into the culture, mores, values, beliefs and religion is fine and in fact encouraged . However, multiculturalism as it is being practiced is a disaster. Look no further than Europe. If there is no assimilation, countries will implode. America has succeeded in the past because we all became Americans. If that ceases, we would become a nation divided amongst ourselves separated by our cultures, and we will fail.
For you see, our language, our laws, our Constitution, our beliefs and values may differ significantly from other cultures. If a person is unwilling to accept our American values and live by them, we will fail.
If immigrants don't accept equal rights for all, we will fail. If immigrants don't believe women are equal with men, we will fail. If Immigrants don't choose to speak English, we will fail. If immigrants don't believe in the Rights defined in our Constitution, we will fail. If immigrants don't believe in, observe and obey our laws, we will fail.
These are some of the very things are occurring in Europe today. And I see the beginnings of some of these things in our own country.
