If a symbol is ambiguous it is not working very well.
Visit an Indian Reservation. Ask an individual aged fifty or older about their experiences with "Christians." Many have had "Paplovian" conditioning against Christianity due to the cruel and wicked behavior of those who claim to be Christians.
We fail to understand that any symbol has the meaning an observer assigns it. God's enemy seizes upon this and uses against us. You are the only representation of a Cross or Bible that some will see.
Pull your head out of the sand and carry His Gospel to the those harmed by false teachers.
I agree on that part, thus is why I did not comment on it.
