I'm a Christian as well. The state recognizing other religions is fine with me and most conservative Christians I know. Their existence and lawful activity is a fact of American life. I have no problem with the state recognizing other religions equally in this capacity because religion is a major part of public life and ignoring it is in fact giving favoritism to atheism, not neutrality.
I also think Scientology should not be recognized as a religion because there is a documentation trail showing that it was deliberately created as a fraud by Hubbard. To my knowledge, no other religion in the US can be accused of that. That is a legitimate basis for the state not granting it protection under the first amendment.
