Why is it Impossible to be RACIST against Hispanics? Why dont PEOPLE KNOW this?

People think Mexicans and Hispanics are all the **same** then look at Luis Miguel Mexican singer who is of Spanish and Italian decent, also look at Octavio Paz, Adela Noriega, guillermo delToro, and Gael Garcia Bernal...THese are Mexicans who are wWHITE!! because more than 10% of mexicans are actually white..also there are few black mexicans such as Kalimba, soo before you think mexican is one specific thing look at the many people who are mexican and google their pictures first! Trust me you wont be racist if you realize mexican people are NOTTTT A RACE!! And then there are Most people from Argentina and Uruguay who are predominantely Mediterranean and Norther European decent but there are TONS of races in all of the Americas You can google Fujimi and Peru to see Perus ex president who was of Japanese origin..and Who can deny Alexis Blidel is white? or that Sammy Sosa is black? YET THEY ARE BOTH HISPANIC!!! you cant be racist to a race that dosnt EXIST!
