Not sharing course outlines is not going to help make this problem better. Better to face those groups head on than hide.

Cool, if you feel that way then go face them. Don't force professors to stand in the firing line in your stead.

It would make finding targets more difficult than just doing a ctrl-f, which obviously would make the problem better just by making it harder to find professors to harass.

Why should professors face death threats head on? What are they going to do differently besides self censor?

It observably does make it better.

A friend of mine was harassed by these sorts of groups for their teaching. They received death threats, hardcore pornography, and gore in their inbox from these chuds. The trigger was the availability of their course material online.
