If you declare a “war” on something—no matter how toxic that something is, no matter how noble you think your cause, no matter how metaphorical your meaning—you are going to have a war on your hands, with everything that implies.
If you want to “fight” something…then you’re going to be in a fight.
What are you declaring war on? What are you hoping to fight?
So much depends on how you say things. It may initially seem so trivial, but it’s not & it adds up over time.
