'White' people have become comfortable talking in front of us about anything. You can easily make them UN-comfortable without risking your job.
First, make them realize that if they're working for someone else, they aren't 'White'. They are Caucasians using 'White-skin' privileges bestowed on them as a result of slavery in the 18th Century. Their job was to keep all us Brown people under control and subservient, all the while, they, too, were subservient to their 'Masters', i.e., rich European landowners. As long as they felt that they were 'above' us, they felt secure in their positions of authority. All that is changing, slowly but surely, but most of them ain't 'woke' yet. That's why you'll still see the errant Caucasian rant about 'n1ggers' and every other ethnic group that isn't European.
The truth of the matter is, 'White' people consider Caucasians no better than 'n1ggers'. If you want proof, read this book.......
Chinese, Mexicans, and a few other ethnic groups were also considered 'White'.......if they had enough money or land.
