Nobody said you couldn't say them, it was that open bigotry is something everyone associates with being a person of low class. When it's used by the upper classes it's as a divide and conquer tactic to keep the lower classes from focusing on the group that's actually exploiting them.

The normalizing of open bigotry is a kind of 'death of despair' for US culture: it indicates that, en masse, people have given up on elevating their class in society and being better people, and have decided to just wallow in it. Blaming the 'other' isn't anything new, it's the basic lazy tribal default and it's the 'easy' button for a culture that simply gives up.
