I think some people here are confused as to the situation that is going on in Mexico and why it is an issue.
The term Hispanic is misleading because the only "real" Hispanics are those from Spain and Portugal. The original Latin speaking countries are Spain, Portugal, France, Italy, and Romania.
The term Latino or Hispanic is generally reserved today for people of Central and South American descent (with the exception of Suriname and Belize).
The issue isn't necessarily against Hispanics or even Latinos, first of all Latino and Hispanic isn't even a race but a language group of people, you have white hispanics, black hispanics, mixed race hispanics and native american hispanics.
The issue with the illegal immigration into the US is for a variety of reasons, first for those unfamiliar, Texas declared it's self a republic which was formally apart of Spanish Colonial Mexico and delared it's self independent as a republic, Texas wanted to be it's own free country basically and this sparked a war between Mexico and the US who annexed Texas, Mexico saw Texas as a rebellious territory that they would take control of Texas even though the majority in the state wanted to be independent.
After the US won the war against Mexico, they forfeited territory to the US with the signing of the Treaty of Guadalupe Hidalgo, this gave the US government control of those territories and the US paid for the remaining territories. This was a treaty which the government of Mexico signed similar to how Russia sold Alaska to the US.
Today, the issue with illegal immigration primarily is coming from central America and Mexico, you have people who are trying to get in by human trafficking to work and send money back to their families, they try to stay here by marrying a US citizen or having a baby so the child can't be deported hence they can't be deported.
The other illegal immigrants are drug dealers who are coming here to fuel the war on drugs by also using human trafficking and smuggling of narcotics into the United States to pay for their operations to overthrow the Mexican government, these cartels are a huge problem because they are out for blood and are willing to poison our population purely for profit.
You also have those who are coming here using benefits from the government and they are stealing identity and not paying taxes, this is wrong.
The other group are the extremist Azlantist or Mexicana movement who believe that the entire Americas belongs only to people of indigenous background and all white skinned people should be killed or removed.
Granted there's a big difference with a American of Mexican descent. I think there's plenty of good hardworking people from Latin America but there are also a lot of bad people that are ruining it for the good ones.
