If you wanted to get rid of the assholes - incredibly difficult, because they take many forms - you'd have to reinvent corporate culture in the US to make it less extractive and performative and more substance-based and cooperative.
The people who are loyal to the company, and believe in the mission, and obedient to the leadership, they are the ones most likely to amend their language and adopt the new terms. They will apologize for their mistakes and correct themselves. This will be looked upon with widespread favor.

Others will not comply. Perhaps they are too old and set in their ways, or they just don't care about other people's feelings, or they are disobedient to the leadership already, and disloyal to the company. For whatever reason, they are the ones who will begin to distinguish themselves with language. When the rest of the company has adopted the acceptable terms, the Missing Stair people will be left behind. Then, they can simply be treated as Missing Stairs.
The bad apples don't necessarily need to be fired or exiled. Simply having a way to distinguish them in a crowd is very helpful in any organization.
