1. "I would say that it means the difference between people’s skin color, eye color… basically..." Should it be "difference(s) between people's skin color(s) and eye color(s)", grammatically? or "differences among people's skin colors, eye colors...", logically?
2. "They might completely balance each other out," Would "They might be completely opposite" come out more natural?
3. "Diversities means the difference between looks and personality" Sould it be "personalities" for consistency?
4. "If there was no such thing as diversity" "were" is more approperiate.
5. "Diversity can also be the difference between jobs, and between religions" Should be "among" instead of "between"? Again, either "a difference" or "differences" should be there for the sake of consistency.
6. "Their mom could have green eyes, and their dad could have brown eyes, but wears tinted contacts and pretends to have hazel eyes. " Ambiguity. Who wears tinted contacts? Mom or dad?
7. "In a way, diversity is the borders that separate our identities from others, from our names, to our likes and dislikes." Would "be our likes or dislikes" be more logical?
