1. They have no morals. (It's not enough to obey laws and be kind.)
2. They're tools of the devil. (Even though they don't believe in him)
3. Untrustworthy - Anyone who doesn't fear God is capable of anything.
4. They're going to hell. If they won't convert avoid associating with them.
5. They have never read anything in the bible or attended church.
6. The demand for separation of church & state is an attack on religion.
