For several years now, the Atheists, Humanists, & Agnostics at the University of Wisconsin-Madison have put up displays in the State Capitol.
For example, to counter the Nativity scenes around Christmas, they put up signs honoring gods from Game of Thrones. They honored the Flying Spaghetti Monster over Easter in 2015. Last year, they went with Jedis.
They’re taking their own advice, too. The sign doesn’t include a single mention of the word “Easter.”
