I had to check the date on this story to make sure it wasn't April Fools' Day:
Homebuilders scrap 'master bedroom' because of racist, gender-biased connotations. "Master bedroom" replaced with "owner bedroom" in floor plans. ...
Why? In large part for exactly the reason you would think: “Master” has connotation problems, in gender (it skews toward male) and race (the slave-master).
Which called to mind something Daniel Henninger said in today's WSJ:
Political correctness—the silent code that decides whose side of the story gets elevated and whose side gets buried—has been a blunt but effective weapon, which the dominant liberal culture has used to achieve a lot of victories over "them" the past 40 years. But the wins have come at a price. That price is the return of an unmistakable, growing and potentially destabilizing bitterness in American politics.
