With this experience I have started a growth path of thought and of English language, for this I have to thank the BNC staff and my English teacher.
I have understood the importance of the walls both physical and moral walls that can arise between peoples of different ethnic groups such as Americans and Mexicans.These differences between peoples can lead to episodes of racism and discrimination. Moreover many Mexicans are often wrongly accused of drug dealing in the United States,but I think this is just a lie to accentuate hatred towards Mexicans, who emigrate to the states only to live a better life.
History teaches us that in the world there have already been episodes of circumscription between two peoples or even between citizens of the same city as in Berlin in the second post-war period,but the reasons for that wall were only political and not racial or discriminatory as in the case of Trump's wall.
In my opinion, walls of any kind (moral and physical) are wrong and create discomforts between people of all types and races.Also slow down the evolution of the human race.
