I agree completely we must say what we are for, for all the reasons you mention. However, as a former advertising manager, I’m also sensitive to an extra layer in the communication, which is how hard you make your reader work to absorb your message. For example, if you want to communicate via billboard, the rule of thumb is no more than 7 words—people won’t absorb more than that as they drive by. If it takes 200 words to say what you to say, don’t put those 200 words on a billboard, find another medium—or find a way to say what you want to say in 7 words. That is just the reading-time constraint—others are vocabulary and comprehension. While these are real constraints, they are also metaphorical—your words have to meet people where they are. Your ideas need to be in forms they can put in their minds next to their other ideas. “Defund the police” was less than 7 words, but it broke all the other rules, and so it backfired.
