You’re right to reject the logic behind that because it’s nonsense. Its not making sense to them because they still presume some kind of good faith when it come to these sorts of things.
The reason we haven’t built more nuclear power stations is because oil, gas and coal companies will make less money, if we build more nuclear power stations.
They have the means, the motive and they have a well recorded history of being that cartoonishly villainous. Nothing else makes sense.
Three Mile Island and Chernobyl really did change things. Prior to those incidents there were plans to build over 50 more nuclear plants in place which got canceled as a result. Currently oil and gas industries will do all they can to keep nuclear from making a come back, but for a long time they didn’t have to do shit thanks to those catastrophes.
