When some evil so and so comes and tells me uninvited that I and my family, including my grandchildren, deserve to burn forever in a lake of unquenchable fire because they are so evil for not accepting their zombie god's sacrifice, I am gonna have a problem with them.
How dare they say things like that?
When they tell me my niece deserves to be stoned to death, because she married another woman because their bloody book of immoral bronze age fairy tales say they deserve to die and burn forever...I am gonna have a problem with them.
When they and their fellow believers get together and petition (a nice euphemism for bribe, cajole and blackmail) elected legislature in to forcing their twisted morality on to the population as a whole ...I am gonna have a more than problem with them and I am going to do more than argue with them!
