Many believers pick and choose the "scriptures" and beliefs they follow. They can be friendly, but belief can quickly turn hateful and even deadly with believers. In your example, it is not their religion, but their morals that keep them from hating or attacking you. That can change if they put their beliefs above their morals or even common decency. It is a good thing that they don't take their Bible literally. These type of believers are usually just trying to assuage their fear of death and non-existence after death.

Here are a few examples for believers to follow from their own Bible:

"And the man that commits adultery with another man's wife, even he that commits adultery with his neighbor's wife, the adulterer and the adulteress shall surely be put to death." (Leviticus 20:10)

"If your very own brother, or your son or daughter, or the wife you love, or your closest friend secretly entices you, saying, "Let us go and worship other gods" Show them no pity. Do not spare them or shield them. You must certainly put them to death. Your hand must be the first in putting them to death, and then the hands of all the people." (Deuteronomy 13:6-9)

"Anyone who blasphemes the name of the Lord is to be put to death. The entire assembly must stone them. Whether foreigner or native-born, when they blaspheme the Name they are to be put to death." (Leviticus 24:16)

"For six days work is to be done, but the seventh day is a day of sabbath rest, holy to the Lord. Whoever does any work on the Sabbath day is to be put to death." (Exodus 31:15)

"He who strikes his father or his mother shall surely be put to death." (Exodus 21:15)

"And he that curses his father, or his mother, shall surely be put to death." (Exodus 21:17)

"And if your eye causes you to sin, gouge it out. It's better to enter the Kingdom of God with only one eye than to have two eyes and be thrown into hell." (Mark 9:47)

Eric Hoffer explains why people reject themselves and others in order to be "saved", "By renouncing the self we are getting out from underneath the only burden that is real. For however much we identify ourselves with a holy cause, our fears on its behalf can never be as real and poignant as our fear and trembling in behalf of a perishable self. The short-lived self, teetering on the edge of irrevocable extinction, is the only thing that can ever really matter. Thus the renunciation of the self is felt as a liberation and salvation."

This is why they "feel" saved, more extreme believers "feel" that by rejecting themselves and others more, because of their Bible's commandments, their salvation is more secure.
