@philosophy Indeed it is such a fallacy. People seem to believe that If-then statements are equivalences and therefore bidirectional. They are not.
Additionally, even if they were formally correct, the statements are not sound. The designation "Christian" contains mutually exclusive practices based on the actions and words of their members; therefore, their conditional is not sound.
What they mean is, "If I (my group) were in charge, we would ban the things I (my group) is against."
