It’s the conservative parties like the CDU/CSU and the FDP that have switched to populism and disinformation to stay somewhat relevant in the age of climate change.

They haven't "switched" they were always that way. When in the 90s "Die Republikaner" and the "DVU" came up (like AfD but not as successful), they were riding on a wave of racism and anti-immigration speak the CDU/CSU started. It was them who invented words like "Schein-Asylanten" (Sham Asylum Seekers), "Asyltourismus" (Asylum Tourists), they wanted to change the Grundgesetz to limit asylum. That was 33 years ago.

And for the Greens as their "enemy", it was like that from the beginning in the 80s, I was there. They started laughing at the Greens and then went very fast on to attacking them furiously.

Already in 1986 Strauß told his voters red-green would take away their cars and their freedom. His speeches are everywhere on the internet, of course very famous with the far-right today.

I am 57 now and I feel so trapped in a circle where the conservative parties stop progress at every step, a progress that was already known as necessary in 1980. 40 years lost.

Sorry for me rambling, I needed to get that out of my soul today.
