Rather than that, it’s a veiled NIMBY argument. They don’t care that nuclear, gas or coal power plants look uglier - they would if they would stand in their backyard.
They similarily don’t really care about the optics of wind turbines, but they are afraid of javing them in their backyard, which is much more likely than a power plant if you don’t live near a river
I remember passing a cooling tower with my parents while traveling as a child, they pointed to the billowing steam coming out and said something about how the government is installing these plants to pump that radioactive gas into the air and “control” us.
I grew up, looked back at it, realized how dumb they were… but also realized how common that level of ignorance and contradictory thinking actually is, particularly in the US.
