Depends on the research. For some areas such as gender science, they swooped in and literally burned decades worth of research [1]. And fwiw, even medicine was considered political - the term "Schulmedizin" was popularized by the Nazis who preferred esoterics, homeopathy and other quackery.

IMHO, it's more than warranted to call out parallels between events back then and events happening right under our noses today [2], not to mention the increasing and worrying trend of book bans [3].
