That's fair - and I'm not advocating everyone just assume they know what's going on from a video - but what I am saying is to use the available resources - video, testimonials, hands on, etc. . .get the experiences you can, compile them.
Both Dan's comment "You don't know what you don't know" and Ushiro's "impediment to learning is what we already think that we know" I think speak a lot to this. I used to be the poster child for getting out and meeting people. I will get back to it in the next year, hopefully.
But on that topic - I understand where people don't want their idols maligned - or even perceived to being maligned. But I'd really like us to get to the point where someone can give an opinion or assessment of someone else's skills (respectfully, I'd hope) without getting attacked or everybody being fast to assume that they didn't "get" what was happening.
But that's just me
I know that you are talking about some people's perceptions of Ushiro Sensei. I have always encouraged everybody I know to get some hands-on with him. I would love it if some people could explain some of the things that he can do. I simply object to behind-the-back, negative comments spoken from a place of no experience. If people want to come out and say that from what they think that they see......, fine, no problems, but then that person should follow it up with some hands-on to confirm one's opinion. That to me, is the basis of integrity. If you put it out there, do so for all to see and then back it up with experience. You and I are ex-wrestlers. We both know that at the end of the day, the person's hand that is raised is from what really happened and not from conjecture.
