Kevin where are you from before taking the plunge into the armpit of the nation?
Well I have to attest, that there are some of the very people we are talking about in my new dojo here in Pasadena. You cannot learn anything from a "sluggard". For, in my mind, a "sluggard" is someone who spirit is not in there training. These people display this "sluggard" trait in different ways. Some do not try as hard as they could/can (physically), others do not cooperate with techniques and impede the learning process.
It all comes down to the fact that these people are disruptive, and sometimes even destructive, to the aikido environment. It is something that should not be promoted in the dojo.
