If you are Christian and feel the need to set a JW straight, start of with some common footing by establishing what all you agree on:
- The Bible is God's Word
- Homosexuality is an abomination
- Women should know their place in the family and at church
- Teens should feel guilty about masturbating
- The human race is only 6,000 years old
After that you can start splitting hairs about how drinking fake human blood ought to be done.
