Yes Judo has been altered from it original form. What you see in the Olympic is not the original Kano Jiu-Jitsu or Kano Jiu-Do.
And not huffy at all. Based on your statement "I don't do TKD" I just found it quite profound that you would example something that you don't do. I would have stated the same thing if you had instered any art in place of TKD.
Just going on what I see and hear from people. Just because someone doesnt do an art, doesnt mean that they cant make an observation. I'll defer to Steves post.
