Here's why:
* "Indians" is a broad term referring to people from the Indian subcontinent, which encompasses a diverse range of cultures, languages, and ethnicities.
* "A group of Indians" is a neutral and respectful way to refer to a collection of people from India.
* Specific terms like "a gathering of Bollywood fans," "a delegation of Indian diplomats," or "a community of Tamil speakers" are more accurate and appropriate when describing a specific group of people from India.
Instead of using a general collective noun, focus on being specific and descriptive. This avoids oversimplifying the diversity of Indian people and promotes respectful and accurate language.
