How does Crevecoeur contradict his own observations about America's diversity and equality? Select all that apply.

Hello. You did not show the answer options, which makes it impossible for the question to be answered in a specific way. However, I will try to help you in the best possible way.

The way in which Crevecoeur contradicts his own views on diversity and inequality in America is through the change of tone between the first and the last letters. That's because he starts the letters with great pride in being an American and being able to live with fellow citizens worthy of so much admiration. For him, America is a spectacle and deserves to be celebrated. However, that tone changes in the last letters, becoming highly pessimistic. Crevecoeur, begins to report American society as inhuman and intolerant, which enslaves those who are different with great cruelty and injustice.
