Generally speaking, they are not at all like what what you've described. So, no, what we see too often here is not the mainstream of the evangelical community.
The evangelicals I know enjoy a good laugh... maybe even a snicker at an off-color story. They might take a drink every now and then, even if they don't keep liquor in their houses. They pray for guidance and they want to bring people to Christ, but they also pray for people they disagree with... and not like "Dear Lord, please help that Trump supporting neighbor see the light before you smite him, as he so richly deserves!"
They like to hunt. They don't like war. They pray for the government, but don't completely trust it no matter who is in office. They are conservative, but the definition of conservative is not cookie-cutter.
Mainly, they just want to live their lives in peace. They want to have enough money to live comfortably, leave a little to their children, and give a little to the Lord.
These are not snake-handling freaks, as is so often portrayed in the media. They are normal people with great faith.
