It’s easy to point out the problems with conservative border policy. Changing someone’s mind is not so easy.
We welcome immigrants in the USA, just as it should be. However, people who come here should rightfully bring their education, good health and financial or intellectual capital–and do the paperwork to get here legally and honorably.
Invading Mexican hordes do not offer any of that. They bring, ignorance, disease and poverty to the US. People around the world should be unhappy about that… all the illegal aliens are stealing the opportunity from qualified legal immigrants to be here.
Some Mexicans and people from Central America immigrate to the US legally. They are welcome, of course. The others are not.
