Re: Acceptable Aikido Vices?
A vice to me implies a moral failing, and I don't see how moderate drinking or using tobacco or drugs (assuming you are not putting others at risk by how you do so) is a moral issue. Health yes, moral no. And on that basis, it makes as little sense to me as asking if it is acceptable for an aikidoka to skip a health screening like a cholesterol level or a PSA test.
A person who trains in aikido is a person who trains in aikido, one of many martial arts, along with everything else that person does in his life. Aikido is not a religion and lays out no specific rules of conduct off the mat. Anything a person draws from it of a personal or spiritual nature or as a guide to living is that person's interpretation and not necessarily what anybody else draws from the art.
