Somebody has been listening to a few too many lefty talking points without the filter turned on.
1/ The United States needs to make English the official language in the United States. Official documents should be filled out in English. Official signs need to printed in English. Anything less than making English the official language creates a fragmentation of our population. This is something the left consistently attempts to do. The intention of our founding fathers was to create a unified nation. In 1782, the Congress ratified E pluribus unum as the motto which stood for, "out of many, one". A citizen of the United States should not have to learn another language in order to function in society. Living in Lynchburg, this is just a talking point, but in a growing number of locations in our country, it is becoming a reality.
2/ Americans should take opportunities to learn other languages, but not for the same reasons that Europeans do. My aunt and uncle are missionaries in France. My three cousins speak English and French fluently and can also speak Spanish and German. They can communicate the basics in a few other languages spoken in Europe. Their knowledge of these languages is directly related to the proximity of the European countries to each other. However, the countries in Europe do not have a problem stating that people living in their countries need to know their country's language. Comparing our grasp of other languages to those living in Europe is not sensible. Geographically, it is not necessary for Americans to learn another language. However, the opportunities to communicate with people around the world is available to all of us because of technology (phones and internet).
3/ The English language is ranked third (behind Mandarin and Hindi) in the world for native speakers. It is the international language of business. It is also taught more than any other language as a second language. While Spanish is the most common in Central and South America, it is very seldom used outside of our continents except in Spain.
