Science can’t disprove and infinite number of things that are not its responsibility to teach. But again, that sounds like an excellent subject for a philosophy class, no more appropriate for Science than for Math or Spanish or Tennis class.
If our adolescents were compelled to go to Purdue where you encountered evangelical excesses, I’d be more concerned, but wouldn’t conclude that two wrongs make a right.
Teaching non-science in science is like marrying homosexuals. It potentially allows anything in, blurring its methods through lack of standards and corrupting its results.
