Also size or dress does not determine race, size may be characteristic of particular ethnic groups within one race, but also within other races, so size does not predetermine race. There is intolerance between, say, two nations of the white race, it is not racism then, such a conflict can grow on religious, political and similar grounds but not racial. Racism is only about skin colour, so determining one's worth or attitude toward someone based on whether they are black, white, yellow or red.
