Why does rodriguez call himself “an impure american, an ambiguous american “? how does the info about his background affect the persuasive of his argument?

This is due to the complication of the elements of his name, the color of his skin and his heritage which makes the American conversation about race more difficult.

Actually his personal background had a decreasing effect on the persuasiveness of his argument. This is actually what we call a minority effect – people tend to less believe anyone who does not resemble his color or race.

Rodriguez writes in Blaxicans:

I am speaking to you in American English that was taught me by Irish  nuns—immigrant women. I wear an Indian face; I answer to a Spanish  surname as well as this California first name, Richard. You might wonder  about the complexity of historical factors, the collision of centuries, that  creates Richard Rodriguez. My brownness is the illustration of that  collision, or the bland memorial of it. I stand before you as an Impure-  American, an Ambiguous-American.

He claims that there is no logical meaning behind Pure-American concept. He lives inc the US and if it has to be defined you have to be an American or in other words Pure-American, then how many people are living in the USA that maybe they have to check their background. Ironically, it is nonsense because there is no logic behind it. Therefore, Rodriguez buries the claims of Pure-American by these lines.

1.creeping like a snail is a simile used in this poem and it means the child is going to school unwillingly./a child is unwilling to go to school.

2. man becomes very frail and loses his physical strength when he becomes old, so much that his leggings that used to fit him snugly when he was in his youth are now too loose for him to wear, and that his shank has shrunk so much that this worldly stage is too big for a feeble actor like him. although, 'his youthful hose' just refers to his leggings/pants/ to shrink from danger; to shrink from contact.

3.the words "sans" means "without." it is a french word that is often used in english even today. so he is saying that in the last age of a man, the man is without eyes, taste, or anything else. he also says that this is the "last stage of all" and that it is the stage that ends a man's "history."

hope this !
