Let me be the first to point out that you repeatedly misspelled "Barack" and, most egregiously, "Chewbacca."I am afraid that I cannot forgive the second offense.
The FFRF has no problem with secular displays with historically religious roots, such as Christmas trees, Easter eggs, and Chewbacca costumes (Jedi religion). The problem is a display that endorse a particular religion to the exclusion of others. You can read more about their stance in their FAQ. I think you'll see that they're pretty reasonable and not the hypocritical Christian-haters that Mariano paints them to be.
