I believe that mankind can be divided up into 8 races
Are you really that confident? What would these 8 races be?
well, to list exactly the top three there would be i.e. Asians, Blacks and Whites. Now, if I were to list the other ones, well, to list exactly the top three there would be i.e. Latinos, Mixed/Multiracial people, and Indians
People are hard to categorize and it is not good to put them all in some box. People can be different even within the same race so stereotyping them is not good.
What do you mean?
I mean that there are other quantifiers and differences between these races that you can't just shoe horn them into specific groups. People might be offended to have their cultures lumped in with another race just because they look the same. You should really think about what it means to be a race and how cultures vary.
