It's not a nice thing that an elected offical appears to endorse one example of traditional religious expression while rejecting another traditional religious expression which has also entered secular life.
Not a nice thing at all. For any of us.
No, you said Now I'm even madder than I was! I normally would think that lighting the menorah is a nice thing but not now. Why do the Jews get to call it Hanukkah but the Christians can't call it Christmas? This isn't "inclusive", it's divisive.
I’d suggest you take your anger out at the mayor rather than the Jewish community. From other articles on this incident, I understand the Mayor has set up a crèche at Denver City Hall. If you don’t let him know how you feel that will be gone next year too.
An elected official attending and participating in an event sponsored by a community organization is not the same as the expendature of government money on proselytization for a particular religion.
