this ignores the key issue that in Germany, there was already an extensive and perfectly functional nuclear industry. In other countries with no nuclear infrastructure, renewables are definitely the better, cheaper, more scalable choice - but countries which invested big many decades ago are in a different position, and Germany’s deliberate destruction of their nuclear capabilities has left them dependant on fossil fuels from an adversarial state - easily a worse situation than small amounts of carefully managed nuclear waste while renewables were scaled up.
Whether they were condescending or not “militant athiesm” is a ridiculous hyperbole - people are free to believe whatever they want, just as anybody else is free to comment on that belief system when theyre not a part of it.
