The spirituality that O'Sensei possesed and the courage he had to express his spirituality is greater than most of use will ever aspire to obtain. Rather, I believe spirituality is expressed through our actions. If we limit our spiritual expression to physical technique, then by our actions we limit our commitment in spirituality. I am very appreciative of those aikidoka that posess the courage to outwardly express their spiritual beliefs beyond simple exercise.
While I agree that O-sensei's aikido was an expression of deeply held religious beliefs, and that in America things are a bit different, keep in mind that this whole issue is a lot more complicated than the binary of has spirituality / doesn't have spirituality. Omoto-kyo neo-shintoism, more common forms of shinto, Zen, Shingon, New Age, Christianity, Taoism, Humanism... I've at least heard of, if not seen, people genuinely try to connect aikido to all of these forms of spirituality, some more overtly than others.
To the degree that aikido is a vehicle of spirituality, it appears to be pretty agnostic about which form of spirituality it carts around.
