years ago Dennis Hooker sensei said "Uke does 50%. Nage does 50%. That makes 100% aikido." so half of the time, as uke, we learn how to fight/attack; the other half, we learn how to defend. if we don't attack well, then our defensive sucks (which is a technical term of getting our ass kicked to kingdom come). to say aikido has no fighting is to not doing uke job. it's all about fighting and resolve such conflict, sometimes hard, sometimes soft and anywhere in between.
you know i have not encountered a martial art that spent so much time rationalizing their action and trying so hard to come out smelling like roses; yet ignoring the manure that makes the roses smell so nice.
