I don't doubt that for a minute. I am s#*t at ukemi but I have no problem initiating it. Based on my initial experience of Aikido I had a similar view to you. What I have experienced since changed my attitude completely. Now, if I could only retain one of my martial arts it would probably be Aikido. I haven't had a problem using it against anyone, but then you do keep telling me that my training isn't the typical.Eh, judo and and Bjj take a lot less time to become proficient at than Aikido. About a year's worth of training in Bjj or Judo should yield you some satisfactory results. On the other hand, I've seen black belt Aikidoka not being able to perform their techniques against resisting opponents. And when I say not being able to perform, I mean complete and total shutdown of their ability set.
They have some great ukemi though.
How appropriate would your normal BJJ or Judo be in a psych ward?
