I wasn't, in particular, stability should be a no brainer - yielding or not.
There's nothing in the quote you cited that says moving or yielding is a bad idea. Nobody talking about push tests has ever said that moving or yielding is a bad idea. Give up the straw man.
Anderson Silva is great - that doesn't mean that he's automatically good at everything. There are plenty of great fighters around who use no internal methods at all, nothing wrong with that, everybody chooses their own strategies.
I'm not sure anyone is disputing anything you just said. I certainly am not.
I think what consistutes "internal" and certainly "aiki" is not well defined and may be up for debate... but maybe not!
No straw man here... I didn't say anyone said anything. I just said it confuses the converstaion. I'm trying to get to the nitty-gritty. And my guess is we all have much more in common than we have different.
But that's just me!
