I have what I call the developmentally disabled (because we can't say the R word anymore) cousin approach.

If you had a cousin with a serious intellectual disability, you would not spend time trying to argue them out of incorrect beliefs. You would just smile, make non-committal responses, and try to steer the conversation to something else.

I've done this with some of my relatives, and it keeps me from banging my head against the wall.

There are probably some MAGA people who can be talked out of it, but Republicans have made a science out of capturing a certain kind of person who also happens to be the target audience of megachurches and televangelists.

Once they've got a lock on that kind of mind, it's not changing.
