Lessons from the atheist nativity "display"?

Hum, I have been following this story on the news. This is public ground,I feel Christians have the right to display a Nativity scene. It is a display, not an attempt to convert people. I would have no problem with other religious displays on public grounds. The opportunity should be equal for all who want to participate. I am not threatened by the atheist nativity "display". The man who placed it there has his opinions, I have mine. In think, this would be a much better world if we could learn to respect the values of others.
