Yes, because I read Inherit the Wind in middle school.
How does "White Supremacy" come into the story, or the denial of evolution as a whole?
White supremacists hate the idea that they could have had non-white ancestors. Belief in a white Adam & Eve is much more in line with their world view. Non-whites were created by "the Curse of Ham". https://en.wikipedia.org/wiki/Curse_of_Ham
Even if we correct the logic here, and change the conclusion to something like "All people who dismiss evolution are white supremacists", that would still be disproven by counterexamples, like the many non-white people who don't believe in evolution.
"Acceptance of evolution was lower [than in the US] in ... Singapore (59%), India (56%), Brazil (54%), and Malaysia (43%)"
