How successful have conservatives been in achieving their goals of defending "American" culture against an influx of immigrants in the 21st Century?

Not very successful

Explanation:

The 21st century has in fact seen the highest influx of immigrants in the United States of America with the American culture changing and evolving based on the diverse cultures and religions of immigrants that have come to become Americans. However, the core American culture remains the foundation of these other cultures- freedom of speech, freedom of religion, human rights, political correctness, and healthy competition are some of the practices that's still a solid part of the American culture.
