Been dealing with this on various forums myself.
Most people will listen if you explain the facts, but an unfortunate portion of the anti-nuke crowd senses that there is blood in the water (literally, sad to say) and will not stop screeching.
And of that group a smaller portion will screech anything that pops into their heads.
Have to deal with them as best as can be done while not letting them derail the subject with their fantasies. (latest: spent fuel rods in cooling ponds have been launched like ballistic missiles into the atmosphere)
I wonder if they will ever be able to realize that, as well-meaning as they may be, they are dancing to a tune the oligarchs arranged?
