I'm a layperson like everyone else here, so I'm just going to rely on the fact that fusion research is ongoing, well-supported by government and private sector investment, and is an active area of research for hundreds or thousands of intelligent and sane institutionally supported academics, as reasonable and practical justifications for my belief that fusion is not quite as problematic as laid out in Lidsky's dated and superseded work.

However, for a sketch of how to address the talking points of the more strident objectors one encounters in the wild, one can perhaps turn to https://fire.pppl.gov/fusion_critic_response_stacey.pdf for some ideas. Cheers!
