Yes and no.
Ultimately though, the fact is that if anyone wants to actually follow the holy text of any abrahamic religion, Christianity, Judaism, or Islam, is going to be a radical utterly incompatible with modern civilized society.
But most people aren't because they don't take it that seriously, or they find some justifications for why parts of the book are figurative or don't really matter, or something like that.
Most of the time people don't really believe in the religion as it's defined in it's own text. Most people have their own belief system, their own moral code and philosophy about the universe, and religion presents a comforting idea to reinforce that. They believe it, because they think it says they're right, because it affirms that their moral beliefs about the universe are correct and real, as well as providing comfort with things like an afterlife and the universe having a plan and things of that nature.
And this is true for everyone from the middle american good-christian-mom to radical members of ISIS. They believe in it to reinforce their already held beliefs.
There's nothing inherently wrong with it, but it allows people to not question what they believe in, and gives them an excuse to justify horrific things. Such as ISIS, or when people abuse and murder gays for being sinners, or don't teach sex education, or things like that.
Very few people REALLY believe in their holy text, they just believe in a version of it that supports their way of life, whatever that may be.
