Bad ideas in politics should be argued about, particularly if they are gaining traction and have backing, because then there's a decent chance they will become policy. People who tune out of politics because of polarization and toxicity are letting the bad ideas win.

Bad ideas in fields of expertise need to be discussed to the extent of keeping the field free of bad ideas as much as possible. Biologists will sometimes point out why intelligent design is not a good scientific theory for example.
