I think a lot of this starts honestly, with someone who can do a technique against resistance teaching it to others. One of those "others" then teaches it, but hasn't worked with resistance, so adds a bit that works well and seems really nice with a compliant partner. This continues a few generations (of students) and can quickly lead to techniques that seem like they'd require time stoppage to work.Do you think they actually think this stuff through or do you think they think it through with 100% belief that something like that is easy? May they know the risk and just assume. That anyone who believes what they just sold would be an easy sale on some martial arts classes. Sort of like. "If you believe the crap I just showed, then I know I can take your money."
