Spaces in the park are for sale for whoever wants to buy them to set up any sort of display for Christmas. The Atheist group in question wanted to make a point and bought 18/21 spaces, planning to leave them totally empty, again to make their point. The church group that normally does the same thing got pissed and asked the went to the City, demanding the city refund the money and open the bidding again(so that they could buy all the spaced). The City refused. The Christian group took the issue to court claiming the Athiests were jerks for what they did. The Court found that both sides were just incessant crybabies that this year nobody gets to put anything on display, refunded their money, and closed the park to displays.
So yeah, the Atheist group played the game and won, and the Christian groups were sore losers and cost everyone everything.
Why are Christians never satisfied that they are already the largest, most powerful religion in the US with significant implicit power over law and culture? Christmas is already recognized secularly as a holiday, one so heavily ingrained into our society it consumes our lifestyles for a quarter of the year, to the point where other religions' holidays aren't even recognized unless they fall within the 'holiday season.' But no, if they can't get special privileges and display their symbols in public spaces, they're being 'oppressed.'
