It's also not really an issue that nuclear is free from. It's very difficult for nuclear to follow demand and it is not as reliable as can be seen with France's current struggles.
All of that would be fine, there will always be extremists (and to a degree, we need them) and if you seriously believe in the cause, more power to you...
... the real problem is that left wing has adopted this extreme green position as one of its core elements. Now all the left wingers have to adhere to green extremism, otherwise they're not part of the team. In 2022, it is not acceptable for any member of any left leaning party to be climate moderate.
The right wing has abortion and guns, the left wing has green extremism and critical theory. Try to be openly anti-gun or pro-choice on the right wing. Try to be openly climate-moderate or anti-woke on the left wing... see what happens. THAT's the problem. Nuance in politics went completely out of the window in the last decade. It's either extreme A or extreme B. And the other side is not only wrong, it is evil.
