We should remove coliseum and arena from our vocabulary. Should probably tear down the Coliseum in Rome, makes Christians nervous. How about the words inquire, inquisitive, inquisition. Wasn't the Spanish Inquisition used to put to fire those they deemed to have committed heresy. What about the country named Germany. Do we ask it to change its name. After all look what they did!

This discussion on what is acceptable and what is not is simply one group trying to impose its will over everyone so that we conform to a certain regulated way of talking, thinking and behaving. No thanks, and to any person or group that thinks so would you not be much better off,  living and working in North Korea. I am sure you would just relish the camaraderie of the place.
