I would either send a letter to the head of the department or who ever is in charge of him detailing your concerns and complaints or go in and speak to them. He is being very unprofessional, as well as a dreadful teacher, especially if he is not even mentioning that some of his sources are controversial.
This seems to be better advice than what I gave. At least it would give you some degree of anonymousness.
I would not speak to him about it, if you decide to, be sure to have a witness to ensure that this won’t feck you over.
No need to censure yourself Cam

Anyway to add a point, I would keep that voice recording as evidence. And if you confront your teacher about this again, record that as well.
