@layman,
Just kinda for the hell of it, here's a brief summary of U.S-Mexican relations during the 25 years following Mexico's gaining independence from Spain in 1821, courtesy of wiki:
Quote: After its Treaty of Córdoba, thereby obtaining independence in 1821 from the Kingdom of Spain and its Spanish Empire, having been known as New Spain for the preceding 300 years, and after a brief experiment with monarchy, Mexico became a republic in 1824. It was characterized by considerable instability, leaving it ill-prepared for international conflict only two decades later, when war broke out in 1846.
Native American raids in Mexico's sparsely settled north in the decades preceding the war prompted the Mexican government to sponsor migration from the U.S. on its northeast border to the Mexican province of Texas to create a buffer.
However, the newly-named "Texians" revolted against the Mexican government of President/dictator Antonio López de Santa Ana, who had usurped the Mexican Constitution of 1824, in the subsequent 1836 Texas Revolution, creating a republic not recognized by Mexico.
In 1845, the Texan Republic agreed to an offer of annexation by the U.S. Congress, and became the 28th state in the Union on December 29 that year.
[That same year] Mexican forces attacked an American Army outpost ("Thornton Affair") in the occupied territory, killing 12 U.S. soldiers and capturing 52. These same Mexican troops later laid siege to an American fort along the Rio Grande. Polk cited this attack as a so-called invasion of U.S. territory, and requested that the Congress declare war.
The U.S. Army, under the command of Major General Winfield Scott, after several fierce battles of stiff resistance from the Mexican Army outside of the capital, Mexico City, eventually captured the city.
The 1848 Treaty of Guadalupe Hidalgo, forced onto the remnant Mexican government, ended the war and specified its major consequence, the Mexican Cession of the northern territories of Alta California and Santa Fe de Nuevo México to the United States.
The U.S. agreed to pay $15 million compensation for the physical damage of the war. In addition, the United States assumed $3.25 million of debt already owed earlier by the Mexican government to U.S. citizens.
Mexico acknowledged the loss of their province, later Republic of Texas (and now State of Texas), and thereafter cited and acknowledged the Rio Grande as its future northern national border with the United States. Mexico had lost over one-third of its original territory from its 1821 independence.
The military defeat and loss of territory was a disastrous blow, causing Mexico to enter "a period of self-examination... as its leaders sought to identify and address the reasons that had led to such a debacle."
In the immediate aftermath of the war, some prominent Mexicans wrote that the war had resulted in "the state of degradation and ruin" in Mexico, further claiming, for "the true origin of the war, it is sufficient to say that the insatiable ambition of the United States, favored by our weakness, caused it."

There's a whole lot more there, which I'll ignore for now. But here's the gist of what's been said so far. Mexico was known only as part of "New Spain" prior to 1821. There was disputed territory in what is now the Southwest U.S., inhabited primarily by native americans (not spaniards).
After starting a war over it, and getting its sorry ass kicked, Spain actually got paid to end the whole sorry affair, when they really had no choice. Maybe we should have remained in Mexico City, which we had conquered, and have kept the whole country, but that's a different issue. At the time we just wanted a peaceful co-existence, free from future Mexican attacks along the border.
But like Germany (and Hitler) and Democrats after Clinton lost, the Mexicans were never truly willing to acknowledge that they got their asses whupped. They have basically considered the land lost by the 1848 treaty to still be theirs. Their resentment over foreigners living on "their" land since 1848 has not disappeared (or even abated much) in the 170 years since that war ended.
In other posts I have summarized the extreme antipathy of most Mexicans have help toward Americans ever since. Like democrats with Trump, they are constantly dreaming of ways to dispose Trump and re-assert themselves in power (reconquista).
We don't want ANY people whose loyalties are owed to another country coming into American illegally (any more than we did the Germans who came ashore from submarines during WWII). But the last ones we want are those who hate non-Mexican U.S. citizens (gringos) , and who want to overthrow the U.S. Mexican illegals are NOT Americans, and few of them have any desire to become "Americans."
The number of Mexican citizens illegally living in the U.S. has reached staggering proportions, to the point that they now virtually control the whole State of California. Given their "political" clout, they can pass laws which will, if unchecked, allow tens of millions more Mexican citizens to just stroll on in, in preparation for (and in cooperation with Mexico in) the ultimate retaking of "their land,"
Hightor "doesn't care" who they affirm loyalty to, and you, Max, seem to go a step further. You seem to think it's a great benefit that there are hostile Mexicans who illegally reside in our country, and want to see more of them come in.
Well, unfortunately for you, Trump don't play dat.
