Or that you care for a specific audience. I, for one, do not care about any audience members who get up in arms if I use "begs the question" in the sense of "raises the question", for example. The use has become so common, that I expect anyone who finds that offensive will not be worth the trouble for me to try to cater to.
You need to draw a line somewhere, or you will end up spending your life obsessing over unimportant details of what you write instead of actually communicating.
If your omission of what you assume is "unimportant detail" leads to your audience misunderstanding the "important" detail, you actually are failing to communicate.
It may also happen that the one person who you felt was not "worth the trouble" turns out to be someone who will be very important to you one day, like a potential business partner or investor, and who interprets your misuse of language as ignorance.
There's a difference between obsessing over unimportant detail and being thorough, IMHO.
