Final answer:
An argument against mandatory community service in high school might focus on the additional burden it places on students and the potential to undermine the voluntary nature of community work.
Step-by-step explanation:
When formulating a thesis statement against the requirement of community service in high schools, it's important to make a clear, specific, and debatable claim. A possible thesis might be: 'While the intent of promoting community service in high schools as a graduation requirement is commendable,
it overburdens students with additional responsibilities and undermines the voluntary spirit of community engagement'. This statement asserts a stance on a debatable issue, reflects the purpose of persuasion, and is based on an observation that mandatory service might actually dampen the altruistic spirit it aims to foster.
In your persuasive paper, you should further build your case by providing details, such as the already heavy workload for high school students and the importance of voluntary choice in fostering genuine community engagement. Ultimately, a strong paper will collect evidence to support the claim and remain open to modifying the thesis if new information suggests a different perspective.
