Final answer:
No, it was not appropriate for John to discriminate based on language or accent.
Step-by-step explanation:
No, it was not appropriate for John to write "Do not use. Heavy Spanish accent" on her application form. Discrimination based on language or accent is unfair and goes against principles of equality and respect. It is important to judge individuals based on their qualifications and abilities, rather than their accent or language proficiency. Such discrimination can prevent deserving candidates from receiving equal opportunities and can perpetuate stereotypes and biases. By using such language, John prevented the student from getting assignments and violated their rights.
