Language is about communicating ideas. If someone pays too much attention to how "correctly" a communication is worded, then he/she is probably paying too little attention to the thought being communicated. It's analogous to valuing the packaging more than what's in the box.

Having said that, it still grates when my step-son tells a waiter he's going to "do" whatever dish he's ordering. I'm not sure if he's going to eat it, shoot it dead, or fuck it.
