I’ve followed the FuckCars community for a while (started on reddit). Being one of them car fuckers myself I would disagree. There certainly are people there whose thought process doesn’t go much further than car = bad, but boiling the whole community down to that does a disservice to their more important points. I think most people there aren’t so much advocating for less cars as much as they are advocating for policy and societal change toward a world where we aren’t so reliant on cars. Obviously for a massive chunk of the world population (especially in North America) cars are a necessity like you said, but do they need to be? Wouldn’t we all be better off if the world was less car dependent? We aren’t saying that there should be no more cars, just that we shouldn’t continue to design our cities in such a way that you need a car to live.

If you are interested in more about where the fuckcars comunity is coming from I would recommend checking out the youtube channel Not Just Bikes. All of his videos are great but I think this one is a good intro to the channel. I also like this one because it outlines a lot of the specific “first step” type things that could be much better (most applicable to north america). Also, his Strong Towns Video Series is really good if you have the time.

(here are a couple more because I can’t help myself: Why it sucks to grow up in car-centric cities, How American cities are ponzie schemes, and His video about Stroads)
