@Kitchi Link to the bill: https://leg.mt.gov/bills/2023/billhtml/SB0235.htm
The (IMHO) critical part of the bill:
"a scientific fact is observable and repeatable, and if it does not meet these criteria, it is a theory that is defined as speculation and is for higher education to explore, debate, and test to ultimately reach a scientific conclusion of fact or fiction."
If a concept is considered a "theory," it can't be taught in public schools.
