I don't see the rhetoric you are talking about used by mainstream climate change activists; I see reasonable changes:
1) Power most things with electricity instead of fossil fuels.
2) Generate electricity with sustainable technologies like solar, wind, geothermal. (There is division on nuclear power, but many still support that, too).
3) Reduce the amount of power wasted overall. Most people don't need huge trucks. Fewer people don't even need personal vehicles. Very few people are saying "Take away your choice", most people are saying, "stop subsidizing the bad choice, and make the public transport option at least an actual option by fixing the way we build cities".
This also extends to "stop subsidizing rural lifestyles" where people waste energy on driving 20 miles to the grocery store and back and every trip they make, and deliveries, and all of their infrastructure which has a much higher per-capita cost, while cities subsidize them. If people want to live there fine, but make them pay for it, or at least make those costs more transparent.
In other words, subsidize for the public good (environmentally sustainable things) instead of the externalized costs (environmentally disastrous things), and let the market drive consumer choice.
In most cases, really, it comes down to: STOP subsidizing bad behavior and things will probably get a lot better. That is what I think most experts expect.
