Texas Gov. Rick Perry is fighting on the front lines in the so-called “war on Christmas.”

On Thursday, Perry signed what has been dubbed the “Merry Christmas bill” into law. The measure allows schools to display religious symbols such as nativity scenes and Christmas trees so long as at least one other religious image or secular icon is also included.

In addition, the new law allows staff members and students at the state’s public schools to exchange traditional holiday greetings, such as “Merry Christmas,” “Happy Hanukkah” and “happy holidays” without fear of reprisal.
