Think what those people might be like if they didn't have religion to temper their hatred and malice.
Imagine if they were humanists.
What religion teaches that it's okay to be full of hatred and malice?
You don't think Christianity teaches that? Maybe you are referring to scripture as teaching. People learn ethics from experience and example, not words on paper. If the pastor says now go and love one another just after demeaning whatever it is he felt he needed to attack from the secular world, they learn the latter.
The face of American Christianity as seen by the population at large is homophobia, atheophobia, misogyny, and church-state incursion. All of that is apparently OK with the church and many if not most of its adherents as rendered, whatever the words in the book say.
I point out to my wife every instance of Christianity shown in the media - movies, mini-series, television - and it is virtually all unflattering now. The priest is never the hero. The church never does good. The religious are fanatical. Check it out sometime. The priests in the Exorcist were favorable for the church. They were courageous, correct. and effective. How long has it been since we saw that in the entertainment media.
Believers will claim that that is an unfair depiction of real religion based in an irrational prejudice, but even if that were true, which I don't believe, it doesn't detract from the fact that Christianity is suffering from a huge PR problem based in the public perception of what it is derived from watching the news and reflected in entertainment media. In the Sopranos, the priest makes a move on Carmela. I just saw a Law & Order where a Christian denomination had one of its youth rape another to cure her of her lesbianism, although the character Carisi is shown as a decent Catholic. In Game of Thrones, the head priest, or High Sparrow, is a vicious man whose death is grounds for applause. Blue Bloods depicts a pious Catholic family, although the archbishop is a flawed man. But this has become rare.
Compare that to the mid-20th century, when the priest or pastor was depicted as a trusted family friend and advisor, always welcome at Sunday dinner, and who always had words of wisdom.
