People are stupid enough to misunderstand nuclear fission, they'll be stupid enough to simply be told that there is no risk with fusion and to get on with their lives.
Agreed. I think one of the main PR things that would help would simply be to never refer to fusion as a "nuclear" reaction. People already associate the term "nuclear power" with fission reactors, and that's where most of the fear comes from.
Fusion has been portrayed on film/television as a miracle cure for the energy problem. Shoot, even Back to the Future features a compact fusion reactor on the back of the DeLorean.
Fusion is quite simply a completely different process than fission.
