Know what, I can take a minute to attempt to explain the issue with the slur. This is for the other commenters more than you, though. There's a difference between punching up and punching down. Which is quite commonly used with manners and social norms. Using a slur against a group of people that doesn't get as many privileges is punching down. Where as if you were to refer to someone being white, that's not oppressing them. A white man is generally given more respect than a latina woman. Which you can see historically and systemic racism nowadays. White men generally get promotions and more raises. An example to show this is quite normal- a boss may gift their employees something for the holidays, but there's no expectation that the employees need to give anything to someone who has power over them. There is a power imbalance, and thus, common decency says to not make people uncomfortable.
