Back in the late 70s I worked in the Nuclear industry. I also lived a mile or so away from a coal mine. Some local leftists got the mine workers union all fired up against nuclear and they even set up a propaganda table outside a local grocery store. I stopped and talked to some of the miners there and they didn’t know squat about nuclear energy. The lefties told them that nuclear energy would put them out of work. I told them that if the lefties managed to kill nuclear, coal would be their next target.
Sure enough, that mine is now long gone. The lefties don’t give a damn what your fuel source is. They are against anything that works.
The head of National Union of Mineworkers, Arthur Scargill, was a full-blown Communist, who only used the mineworkers for his own personal goal of overthrowing the British government and imposing a Communist dictatorship.
