> Kowtowing to the lowest common denominator shouldn't be done lightly
Certainly not when you put it like that! But you might also call it "communicating effectively with your audience." So maybe kowtowing isn't so bad after all when it just involves responding to the linguistic conventions observed by your readers, and the goal is simply communication.
I also don't know that people who read quotation marks as connoting doubt, in the absence of any other evident reason for them, can fairly be called "the lowest common denominator."
