I think the problem with your question is that, for the devotee, the object of devotion and religious practices necessarily "make sense." It's subjective. An outsider may look upon it as utter foolishness, but that doesn't mean that it is--it's only an opinion, based on the outsider's sense of rational. Again, it's only subjective.

Those that have studied (and those who have had diarrhea) know that the gut has quite a few senses that ought not to be ignored. Thus, the origin of the term "gut feeling."

Finally, as to one's choice in beliefs, I suppose that depends on one's motivations. If you seek social acceptance, your god is popularity, and anything required to acheive that could be seen as a religious practice. (I'm speaking in broad terms here.) The better question is "what do you desire?" From what I've seen, most religions seem to cater to the crowd that desires justification and absolution for moral failings. Others perhaps give people a reason to "carry on" with life. Still others offer understanding into the universe, the soul, or other abstract ideas. For me, I prefer the religion that teaches truth, since, especially around campaign season, there seems to be such a dearth of it.
