Final Answer:
The question of whether Mark Zucker berg should have censored all denials of genocide for other ethnicities is subjective and complex, involving considerations of freedom of speech, ethical responsibilities, and the potential impact on public discourse.
Step-by-step explanation:
Addressing the question involves understanding the principles of freedom of speech and the responsibility of platforms like Face-book to prevent the spread of harmful content. While censorship may prevent the dissemination of false or harmful information, it also raises concerns about suppressing diverse perspectives and impinging on the fundamental right to express opinions.
Zuckerberg, as the CEO of Face-book, faces the challenge of balancing these factors. Implementing a blanket censorship policy on genocide denials for all ethnicities may prevent the spread of harmful narratives, but it also raises questions about the concentration of power in deciding what can be expressed.
