He is irrational if you judge by the standards of the Doctrines of Christ. I mean, you want a list of bible verses to show him? If he won't listen to scripture then,
he's in error. In a delusion.
Is he your neighbor so you are stuck seeing him a lot?
I'd steer clear of talking politics with him.

Just thinking or speaking rationally makes him extremely angry? He yelled at you? Wow.

It happens a lot these days.
Lots and lots of people believe what you stated about Taylor and Trump.
It's not a salvation issue but the guy is certainly in the "idol worship" area... following teachings of men not The Word.

On YouTube there are SO MANY "Christians" who loyally follow dreamers & seers and these ladies will chew you up if you question if the dream was from God.
I mean, they won't listen to reason.
And.. there's NO changing their minds! It's so crazy. They cannot understand how serious this is, to be seduced to follow a false prophet.
I know these kinds people do not read and study the bible.
Many are new age types, calling themselves Christians but they can't be! They are duped by some kind of deception.
They know a few key verses.. to allow for any behavior that they want to do.

What are you going to do? What CAN you do?
