What evidence do you have that the teacher was doing anything OTHER THAN explaining the scientific principles behind a phenomena that you purportedly accept?
Would there be any way to teach the scientific principles of evolution without presenting a “Darwinist” argument?
Could you do so?
You don't think death threats are the least bit irrational in response to presentation of a theory you purport to accept?
Certainly! I would simply refer you to Genesis 1 and 2.
These books do not purport to be "scientific" texts. But it seems to me that all of science — indeed, all of human rationality — is absolutely premised on them.
Whatever the case, read these texts — with an open mind and an open heart.
Maybe if you do, you will learn something new and valuable about cosmic and terrestrial evolution....
