Some Christians don’t understand how their faith can offend other faiths or non believers. They feel that their beliefs are universal and good for all.
So I suggest this simple substitution test for religious offensiveness. Simply take the item in question and substitute it with another faith. For example if we were to change from “In God We Trust” to “In Buddha We Trust.” Do You find that religiously offensive? If you do, then you have to acknowledge that “In God We Trust” might be equally offensive to other faiths.
Another example would be to post a passage or prayer from the Quran on the school or court room wall. If you find that offensive you have to acknowledge that the 10 commandments might be offensive to another faith, or to a non believer.
This quick and simple substitution test can settle all debates about religious offensiveness in short order. Just remember that religious freedom is a two way street.
