Culture wars are a subtle thing to wage, because they determine everything without being about anything. Explicitly political contests are at least ostensibly about some particular concrete thing: you're fighting for or against a specific law or a specific candidate. But how do you fight a narrative, when your enemy is less of a regime and more of a meme? How do you explain to anyone what you're trying to accomplish when you're not trying to get anyone to do anything different in particular, but to renounce their distorted way of thinking and speaking, after which you expect them to make better decisions, even if you can't say in advance what those decisions will be?
Picture me rushing into a room. "People, people! The standard map is wrong! Look at this way better map I found in the literature; let's use this one!"
"Our map isn't wrong. It has all the same continents yours does."
"I mean, yes, but it's a Mercator projection. Surely you don't really think Antarctica is larger than Asia?"
"Why do you care what size Antarctica is? What difference does it make? People are perfectly happy with Antarctica being the largest continent."
"But it's not true!"
"It sounds like you're assuming your beliefs are true. What is truth, anyway?"
And it being the case that no one will die if she gets the size of Antarctica wrong, what can I say to that?
