Would it be abiding to slave morality to ask for the n-word pass instead of just saying the n-word?

Bear with me this is a legitimate question. So in the contemporary era we are bound by a system of ethics not too dissimilar from Nietzsche’s in that the cornerstone values are compassion, tolerance and care for others, including their sensibilities and feelings. It’s from this system we derive common customs such as not saying slurs. However, given that this line of thinking shares the same ethical root and framework within western culture, would Nietzsche not also decry such a system of ethics as “slave morality” as he did with Christianity or to reduce my argument *ad absurdum*, would Nietzsche ask for the n-word pass or just say the n-word anyways regardless of how any one thought?
