Why should the Christian speaker drop Christmas from the seminar title? It&#x27;s his seminar, and he gets to decide what to title it.  In fact, I think it is offensive to suggest that Christians should sterilize Christian history and iconography from anything they produce.<p>If Donald Knuth decided that his Christian iconography was interfering with the message he wanted to send, then it&#x27;s his talk and he gets to decide to change the title.<p>If a Jewish&#x2F;Christian&#x2F;Muslim professor wants to talk about the 9 Lifos of the Menorah, I don&#x27;t see a problem with that, either.
