These far right wing Christians sound like radical Muslims. Everyone is evil except them.
The difference is that Muslims have more radicals and sympathisers than the West. (At least in 2019 anyway). A long time ago Christians were probably worse than Muslims. The Roman Catholic empire forced religions onto countries.
For far right-wing Christians, everyone who does not believe their religion is a Kafir. Just as far right-wing Christians see it as their responsibility to convert everyone to the one true God.
Far right-wing Jews also see themselves as God's chosen people.
Christians stole the Abrahamic religion from the Jews, then Muslims stole this religion from the Christians. Over the years there have been edits to the original manuscript to customize to each one's idealogical needs.
The same type of brainwashing Church sermons to convince them their way is the only way. What is the point of going to Chuch if you can't even understand the few decent morals that can be learnt from religion (although an adult, or even a kid should already be aware of these basic morals). The real reason religious people go to church is to try buy the insurance policy of guaranteed entry into heaven.
Hopefully, the human race wakes up and ditches religion sooner than later.
