I just find it to be beyond silly that a Statehouse would be a place to "celebrate" anything.
I come from a Catholic background and though I'm no longer a practicing Catholic (no longer really even a believer in Catholic dogma/theology, as far as that goes) I still celebrate the Christmas season.
Even if I don't believe Jesus was/is God I still believe he was a great man with a God-inspired and amazing message and I don't think there's anything wrong with that.
On my lawn, next to the reindeer, and Christmas tree, and Santa, and Frosty, I've got a big inflatable Nativity.
I've also got a 60-year-old nativity behind glass in the china cabinet in the dining room.
I don't think there's anything at all wrong with celebrating holidays, any holidays you want, in any way you want, even if your way of celebrating is to be deliberately contradictory of traditional religions and holy days.
But I think there's a time and a place for celebration and frivolity and I don't think the workplace is it.
I don't decorate my office the way I decorate my home.
I think that kind of "separation" is more important when you're a public body charged with representing all of the people, all of the time.
There are roughly 4,200 religions in the world.
Should all of them be given equal space in a public Statehouse for decorating and displaying in whatever manner the worshipers see fit?
Either yes, all of them should, no matter how obscene and offensive any individual display may be, or no, none of them should.
Since, again, we're talking about a place where business is conducted (public business in the case we're discussing, but business nevertheless) I think the rational, adult direction is to lean toward, do whatever the F you want at home, but this building has other purposes than to serve as a place for celebration of religious traditions and ritual.
