This is kind of a BS article.
It paints with a very broad brush and is meant to discredit pretty much any and all Protestants based on a handful of high profile books and personalities.
Article seems to be cherry picking. It’s easy to do with protestants as many mistake them for a monolithic body and then if some “church” declares the rapture is on date X using reasons y and z, then all protestants are lumped in with them. Just as the MSM likes to find a racist “church” and portray all protestants as concealing inherent bigotry etc.
I could not get through the whole article. I’m allergic to straw, see. And the author sets up so many straw men and starts knocking them about so badly that I just could not stop sneezing.
