Ignore them, they're dying off and aren't being replenished by younger brainwashed generations quickly enough to make up for "losses". There's enough to worry about in the real world without these morons injecting their bullshit into public policy discussions.
I wouldn't be so complacent. There are a number of evangelicals trying to outbreed the rest of population as a protective measure and domination effort.
The "Quiverfull" movement is just one name. The Institute in Basic Life Principles is another one that has spread internationally, Generation Joshua led to the likes of Madison Cawthorn.
Shiny Happy People was a very good recent documentary on Amazon Prime about the Duggar family that is well worth watching if you can tolerate the stories of child abuse, sexual and otherwise.
Those groups are pretty gross even before taking the child abuse aspects into consideration. I don't think they'll be able to bone their way out of the change in attitudes toward religion, the numbers aren't on their side (yet) and relying on future generations to stay in the movement seems like a losing proposition. Still a cause for concern though and membership should automatically put them on a watchlist with Child Protective Services or its local equivalent.
Their world view is founded in being part of a persecuted minority, they always feel under attack. Even when they're the majority. Are they scared of the Iowa Catholics and their communion wine or something again?
One interesting thing is that evangelicals always say their values and faith are "under attack" and people despise them.
No, most people have great respect for people of faith and don't despise and attack Christians or any other faith group, but many despise and attack the Republican Party. And the evangelicals have unfortunately managed to tie themselves so hard to the Republican Party that the two have become almost symbiotic. There's a big difference.
I thought it was telling that one of the women interviewed said she won't vote for any Republican who is willing to work across the aisle, because to her that read as weakness. It's impossible to have a sustainable country without compromise. I only hope that demographics shift enough that we can get on with catching up to the rest of the modern world sooner than later. This relative stalemate is intolerable.
