The condescension is deserved. The green movement has done more harm than help to clean energy by blocking nuclear power trying to push energy sources that were not economically viable. This was mainly due to emotional backlash against nuclear energy.
Condescension is actually rude, and for that reason not a smart way to persuade people you're right. It gets you upvotes on Twaddle or whatever, but only from people who already agree with you.
Yes, it is rude. That's the point. It's not to convince people that already have their minds made up. It's to convince people that don't have their minds made up. They see they will be treated rudely if they adopt whatever the unwanted behavior is.
