Sure I think it's misunderstood, but every martial art is misunderstood somewhat, isn't it?
Yes. Also every religion, every musical style, every field of scientific research, and every hobby. In fact, the only time something is not misunderstood by those outside it is when they accept that they can't understand what they don't know. Aikido is certainly not some kind of uniquely persecuted stepchild in that regard, although it may have an unusually high percentage of practitioners who expect or want to be understood. Maybe we need to get over that. Somehow I don't think particle physicists lose a lot of sleep over the fact that no one at the neighborhood barbecue really understands what they do.
