It's kind of all of the above. State and non-state actors have leveraged pretty much every movement there is to their own ends: civil rights, anti-nuclear, pro-nuclear, anti-Iranian government sentiment, pro-Iranian government sentiment, even jazz tours in Europe which were assisted by US intelligence orgs in the 20th century.
It's not a 'bad' thing and doesn't say alot about the core movements - it just is what it is.
Pro nuclear comes from American conservatives. The same people who claim climate change is a hoax. The same people who hate green energy solutions.
Pro-nuclear comes from scientifically informed progressives, definitely not conservatives.
Nuclear IS a green energy solution.
Again. Show us some peer reviewed studies for your claims. A simple search will show you that, according to dozens or hundreds of peer reviewed studies, research and real world examples, a 100% renewable energy solution is feasible.
