Source for that claim? If you had spent half a second researching before blindly launching into “Christians r dum” rhetoric you’d have noticed that they actually teach a course on evolution: https://www.hillsdale.edu/courses/evolution-biological-diver...
It is not clear at all from the course description what that course teaches:
"An introduction to the vast diversity of life from prokaryotic forms to the eukaryotic vertebrate mammals. This course introduces the beginning biology student to all the major groups of organisms and to their fundamental taxonomic relationships."
"This vast diversity exists because that's the way God made them" is perfectly compatible with that description.
Also, from the description of an event held April 11, 2025:
"Are the special creation of Adam and Eve and the evolution of humans over millions of years compatible? 100 years after the Scopes Trial, the debate continues."
So "they actually teach a course on evolution" seems to fall well short of a full description of exactly what they teach there.
For comparison's sake, here is a description of a more typical Evolutionary Biology course:
"Emphasizes the fundamental evolutionary concepts that provide explanations for the diversification of life on Earth. Specific topics include the evidence for evolution, adaptation by natural selection, speciation, systematics, molecular and genome evolution, and macroevolutionary patterns and processes."
