You’ll meet plenty on the left, especially scientists, who are in favor of nuclear. Where I live (Switzerland[0]), the biggest NIMBY against nuclear are the provincial nationalists who are going nuts about installation of a subterranean disposal site in their area (proposed because it is the most suitable site due to geological properties). My turning point with nuclear was about 15 years ago when learning about thorium. Very eye-opening.
[0] - To the grandparent comment, natural born American who spent most of the adult life and all of childhood in the States. Emigrated a decade ago and still keep close tabs. This post is giving me serious flashbacks to the 1992, when Bush called Gore “Ozone Man”. Was that a genesis of the contrarian political differentiation?
