I'm not worried about immigrants. This country was built by immigrants. I'm worried about Socialists.
I would just insert the word "legal" in front of the word immigrant in your statement.
Legal, illegal, what is the difference? They are all erasing the country that my ancestors built for centuries. At least the illegal ones are mostly all Indios and Mestizos who do not achieve political power and social capital like the South and East Asians do.
