ANIMAL NATIONALISM.
If there is something that makes us similar to animals, if there exists a common ground with the rest of evolved species and not so much that fortunately still endures, it is the closed identification with a group, with a way of acting, with a territory, its defense and the fear that other members of the same species will appropriate it.
Fortunately no political ideology yet includes the need to urinate at the borders, however it seems that if it were not socially frowned upon we could arrive at this point. Nationalisms stem from the idea of differentiation. For nationalist ideology to exist, a process of comparison is necessary, and therefore it denies the most real evolution that a human being can have in an undifferentiated way, the inner evolution that is achieved through the intimate need to improve.
Try to imagine for a moment a person who feels free, an individual who accepts and is open due to the self-confidence they have to the customs of others, culture, language, skin color, religion, etc. Imagine that this same character feels independent, and in addition to feeling free also feels the need for others to be free as well. Now imagine that they are nationalist, I bet you can't!. Being nationalist implies the idea of feeling trapped, conditioned and in struggle. Water and oil cannot mix.
We are direct descendants of an evolutionary process for the improvement of the species through confrontation, through grouping. However, no one forces us to belong to that group and we can have the strength and security necessary to build bridges. The inertia of our primitive heritage drags us more toward differentiation and struggle for closed values.
In the past we have had serious evidence of the damage that nationalist ideologies can cause, whether called socialist (national socialists) or whatever they are called. It has also been shown that following this type of ideology is something rather irrational. Again, the weight of our more primitive, more animal heritage becomes clear, and let it be noted that being a human animal is not something negative, it is simply a reality, period.
Perhaps what separates us most from the rest of animal species is the capacity to understand and feel our instincts from a higher plane, that plane they call consciousness, and from that place one can choose different paths.
Ending exclusive nationalisms is not a task that can be achieved through war, nor through political means. The only way to end these remnants of our more primitive past is the freedom of each individual to decide for themselves, and for that it is necessary to leave space for personal knowledge and reflection.

They say this era in general is a moment to awaken, it may be so. Let's hope that those who ask for change do not enter into the same dynamic as that which they are fighting against. The only way to end exclusion is freedom, that of each one of those who make up the group. Each time someone or a country or region is forced against their natural desire for freedom and made to play the game
of fighting it blow by blow, they lose out, since in this way one
oneself becomes entangled in hatred and passions.
The best way to end a force that seeks differentiation is a vigorous push toward social integration, but this is only achieved by providing means to the individual, not to the collective.
