When will people realize that there lots of different ethnic groups & races in Mexico?

Why is that Canadians & Americans can be diverse, but Mexicans are all supposed to have one look or type? According to the CIA website Mexico is 9% White, 60% Multiracial, 30% Indigenous & 1% other. There are Lebanese, Chinese,Turks, Armenians, Blacks,Laotian & Filipinos and many other ethnic groups, IN Mexico, yet people stereotype us all as being "Multiracial & half Spanish" Which is not true at all, the Spanish heritage is more like equivalent to a great-grandparent.
