“Do not judge, and you will not be judged. Do not condemn, and you will not be condemned. Forgive, and you will be forgiven." (Luke 6:37)
Right from God Himself. The Westboro Baptist Church, abusing the right to protest, protests against homosexuality with signs saying things like "FAGS ARE BEASTS" and "FAGS DOOM NATIONS". They're going to Hell according to their book. It seems the members of the Westboro Baptist Church only listen to the things that they agree with God on. This means they aren't devout Christians.
