Why is rac1sm so normalized now,

I just hate HATE to see that people will say jokes About s14very and make fun of it thinking its okay AROUND BLACK PEOPLE TOO, plus when a black artist has the n word in their song, doesn't mean you get to take that as a sign to say that word, that word was thrown at us and we had to call ourselves that for years and YEARS, plus not only with Africans Americans, with hispanic people also ever since the orange peel decided to kick out Mexicans and all hispanics peoples houses, plumbing, yard work, and many many more stuff wont get done BECAUSE OF YALL Mexicans work more then the average population of white people. They work all day and all night to feed their families, give their kids the American dream they haven’t experienced, but they are called “drug dealers, or aliens” which is sooo disgusting and disrespectful to them we aren’t even in ownership of this country THE NATIVE AMERICANS ARE?
