It's fine to change any of those things, but if you're changing them every day, it can get disruptive and expensive.
Mr. Lost, personally, I don't think there's anything "wrong" with someone changing their religion, but if you're constantly shifting from one religion/viewpoint/label to another, this could be a sign that none of the ones you're shifting between are a good fit for you.
It's no skin off my nose if you change your mind about religion... even if you do it frequently. However, I think it's good for people to be happy. If you're happy changing religions frequently, fine by me, but the fact that you're changing them, plus this thread, are signs to me that you might not be so happy this way.
