How clean is Fukishima or Chernobyl or Three Mile Island or anyof the other many nuclear accidents? Plus nukes are a terrorist target because of the potential collateral from radiation. There is legitimate concern that commercial nuclear operations might cut the same corners that the operators down in Texas did with their power grid.
I believe those concerns can be addressed, but arguing that denial is a valid course to pursue is just bullshit. If you don’t believe me go try to get a permit for one.
