Some people are pushing yet another PC lie,
namely, that only dumb or ignorant people have politically incorrect opinions.
If/when you hear that, think of these Nobel-Prize-winning counterexamples:
Robert Millikan (1923, Physics; first president of Caltech; supporter of eugenics)
https://en.wikipedia.org/wiki/Robert_Andrews_Millikan
For an example of the argument for removing Millikan's name from its formerly-honored position at Caltech,
see this letter from Sophia Charan:

For a more positive view of Millikan, see

James Watson (1962, Physiology or Medicine; director, president, and chancellor of Cold Spring Harbor Laboratory; expressed belief that genetics is a factor in behavior (note: merely a factor))
