For those who are Mexican/Mexican-American, is it true that the Mexican slang "Nopal" or "Cara de Nopal" is the Mexican/Latin American equivalent of?

[Anonymous]

a C00n or Uncle T0m (Black person who kisses up to white people or is a wannabe white person)?

I was just googling this meaning and found a few from urban dictionary and a few other dictionary websites to figure out the meaning and it seems to be slang made to take jabs/insults at Mexicans (especially those who look clearly racially Mestizo and American Indian) who act like wannabe "pure White European" and blindly kiss up to White people (Whether to White Mexicans or White people in general) while self hating their heritage and Mestizo or American Indian race.

Yes

No

Depends on how the context is used.

It is a derogative remark on someone's racial features.
It is used mostly by negative people trying to "show the other what is his/her place" on the social/colour scale, either shouted at the person or said quietly among "friends".
The word that may mean U. Tom is "arrastrado" or "lame botas" (boot licker)
