"Why is "Mexican" a "Racist" Term?
Why should this be considered a "racist" issue?"
Good questions.
Once upon a time, there was a biologist, probably in Europe.
At the time there was a great discussion about how precise biologists should categorize the plants and animals they were so admired to encounter. Some of them believed, upon registering life forms for the first time, that recording them as closely as to the actual experience was the right way to go, so they could perhaps continue their studies with the one or with the group of individuals which were so fascinating, not confusing them with others who might be very similar. Others thought that a general description should suffice, and that it was more important to allow for the possible error of their perceptions, so they may perhaps continue their studies with the associations of those one individuals or those groups of individuals. From the discussion, biology admitted the discipline of ecology as possibly both fundamental and also complementary.
Those biologists, however, that decided not to promptly take upon the discipline of ecology, who would focus on a few number of individuals in the attempt to gather the completion of their individual purposes, so the biologists would eventually learn about another set of singular or multiple individuals, this way taking the long, but loyal, faithful, route to ecology, nonetheless composed of the centuries long mainstream development of biology as discipline. Ecology, likewise, also had centuries of its own development, as soon as new forms of life beset the ancient thinking scientists, either in society or by their own.
"Race" is primarily a biological term. Classical, singular-individual-or group-first biology, now uses it and has used it to differentiate large groups of similar individuals who already share many similar fundamental characteristics. For a trained biologists, a dog is easy to be recognized, and so is a cat, a bird, a lizard, a fly, an ant. The reason for which they are so easily recognized by these categorical names is because the biologists have experienced each group through many different individuals, each with their little uniqueness, their hairs, their eyes, their feet. Those differentiating characteristics, shared by all groups, but unique to each individual, by another set of terms, primarily non-biological (colors seen in the open empty sky, or in clear washed stones, for example), is what has made the biological term species be further joined with the biological term race.
A dog is a species. A red dog is a race. That is, for classical biology, which is agreed to develop as a discipline upon the counsel and agreement of the terminological consequences so the study can continue.
Now, if we instead decide to understand how ecological biology uses the term - the only other scientific discipline which can logically explain the association of the term race with forms of life, or with a place in which there is life - "race" does not become categorical anymore upon the unique characteristic of individuals, but instead is established by the discipline of ecology, to be a species.
For ecological biology, race is a species, and green race is a race [in classical biological terms which happen to be inconvenient for the particular description of the species in question].
Mexican, therefore, is a "racist" term, or may be a "racist" term, because it originally parts from the discipline of biology and may also include the discipline of ecology. Life that thrives in Mexico has the potential to be a race upon the inspecting perspective of a classical biologist. In Mexico there are classical biologists continuing the field of their discipline: life. Or, the second possibility to explain why one term is associated to another, is not so because there are ecological biologists in Mexico, but because in Mexico there may be individuals of the species named race by ecologists.
To further clarify, considering the complicated logic, the word race comes from two different languages, used accordingly by two different groups of student initially coming from the same discipline. To one group, after they had already decided to separate, the word race meant "greater precision", to another group the word race meant "plant with branches or vines", both relating to varying and variant forms of life.
