The anti 15 minute city thing is really so incredibly stupid. Anyone who's ever lived in a walkable city knows that it is vastly superior to anything based around cars.
The people who say this stuff don't know anything about it. They live in a world of "scary things" that Fox news tells them about. They learn nothing about 15 minute cities, only that they are "bad" and will "destroy America" so they hate them.
Which is why you get stuff like the picture above, where it shows the exact opposite of a 15 minute city and just says that's what it is.
It's hard to tell what they actually think on it, because it always changes. If they had a concrete position, that could be combated and they could be reached and educated. If their position changes constantly, they can be kept in a perpetual state of fearful, hateful ignorance.
