Like I said, Protestant churches come in many flavors. MANY flavors.

What you’re saying is like, “Every quadrilateral I’ve seen lately has four equal sides and four right angles, I think you’re wrong about them only needing four sides.”

Evangelicals are (generally) Protestants (although “Evangelical” isn’t really any sort of organized body but rather something people identify as), but not all Protestants identify as Evangelicals. Those who preach the Prosperity Gospel would profess to be Protestant or Evangelical, but not all Protestants or even all Evangelicals buy into Prosperity Gospel.

Again, the most progressive denominations of Christianity are Protestant. That said, so are the least progressive denominations. It’s a huge category.
