To be clear, I was not defending coal. But I do have to ask over what time period radioactive coal wastes "kills a lot more people than nuclear," because being alive is fatal. I think the variance matters even if the mean is lower.
Coal kills more people than nuclear over all time periods, including nuclear accidents. The numbers are not close. The death toll attributed to coal is down to a historical low of (low-end estimate!) 7,500 people per year in the US.
