This is anecdotal based on your personal experience. But you don't live in the Bible Belt. Even if you did, humans are hardwired to handle a maximum of about 200 social relationships (
Dunbar's number). Among those, even if all the people you knew well were fundamentalist Christians, I doubt that you would have discussed with all of them openly and truthfully what they thought of Atheists (especially if they knew you were not religious). And since you don't live in a fundamentalist Christian environment, I doubt that your personal experience representative of the 100+ million Christians in the Bible Belt. So let's look at the statistics instead.
Pew Research asked Americans of every religious denomination in every state
how they interpreted the holy scriptures. By definition a fundamentalist Christian is someone who believes that the Bible is the Word of God and should be taken literally. 31% of respondents nationwide fall in this category. Fundamentalism was highest among
Historically Black Protestants (59%),
Evangelical Protestants (55%), Jehovah's Witnesses (47%) and Muslims (42%). Follow the links to see the distribution of the two first denominations by state. They are of course mostly found in the Bible Belt.
The problem I have with Fundamentalists is that, since they take the Bible literally, they believe passages like these:
- Leviticus 20:9 If anyone curses his father or mother, he must be put to death.
- Exodus 35:2 For six days, work is to be done, but the seventh day shall be your holy day, a day of sabbath rest to the Lord. Whoever does any work on it is to be put to death.
- Ezekiel 18:13 He lends at interest and takes a profit. Will such a man live? He will not! Because he has done all these detestable things, he is to be put to death; his blood will be on his own head.
- When men fight with one another, and the wife of the one draws near to rescue her husband from the hand of him who is beating him, and puts out her hand and seizes him by the private parts, then you shall cut off her hand. Deuteronomy 25:11-12
- Now therefore, kill every male among the little ones, and kill every woman who has known man intimately. But all the girls who have not known man intimately, spare for yourselves. Numbers 31:17-18
On slavery;
- Exodus 21:20-21 – "If a man beats his male or female slave with a rod and the slave dies as a direct result, he must be punished, but he is not to be punished if the slave gets up after a day or two, since the slave is his property."
On rape:
- Deuteronomy 22:28-29 - "If a man happens to meet a virgin who is not pledged to be married and rapes her and they are discovered, he shall pay the girl's father fifty shekels of silver. He must marry the girl, for he has violated her. He can never divorce her as long as he lives."
On hating your family;
- Luke 14:26 – " If anyone comes to me and does not hate his father and mother, his wife and children, his brothers and sisters—yes, even his own life—he cannot be my disciple.
On killing children;
- Hosea 13:16 - "The people of Samaria must bear their guilt, because they have rebelled against their God. They will fall by the sword; their little ones will be dashed to the ground, their pregnant women ripped open."
On adultery:
- Genesis 38:8-10 - "Then Judah said to Onan, "Lie with your brother's wife and fulfill your duty to her as a brother-in-law to produce offspring for your brother." But Onan knew that the offspring would not be his; so whenever he lay with his brother's wife, he spilled his semen on the ground to keep from producing offspring for his brother. What he did was wicked in the LORD's sight; so he put him to death also."
- Leviticus 20:10 - “If a man commits adultery with another man's wife—with the wife of his neighbor—both the adulterer and the adulteress must be put to death.”
Now can you say with absolute certainty that there is no link whatsoever between holding such believes and the fact that the crime rate (including homicides) is so high in Bible Belt states? These are people who openly admitted to academics that they took the Word of God literally and 85% of them said that religion is 'very important' for them, so they are not going to take these 'instructions' lightly. Furthermore, those people are poorer (46% earning less than $30,000) and less educated (56% high school or less), two factors that also correlate with higher crime and homicide rates.
Add to this that
gun ownership rates in Bible Belt states are among the highest nationwide (from 29% in North Carolina to 58% in Arkansas, but average in the 40%) and you'd got a dangerous cocktail. In New York State only 10% of people own a gun, about the same as New Jersey (11%), but still higher than Rhode Island (5%). Big contrast with the Deep South.
