maybe a better example would be anything to with "master" "slave" relationships.
An african american woman in the office turned to us and said "maybe it's the master who needs the slave?"
She wasn't really offend or anything and she said it with a sincere smile. She was just calling out our idiotic computer lingo for what it was.
After apologizing feeling like complete idiots we quickly changed our terminology both in words and in the script to parent/child.
