Ironic post is ironic.
Defense of slander and libel is truth.
The onus of proof is on the person making the claim.
This forum should have its ultimate goal be truth. Martial arts truth. Historical truth. Objective truth.
This means identifying non-truths and making them visible for everyone so that no one is thrown off the path.
When people make claims, the onus of proof is on that person to prove it is true.
For example, here is an example of non-truth and non-proof:
Person 1: "Hey, look at me, I am protecting myself with qi power."
Person 2: "Interesting. But it just looks like physical conditioning + stage tricks. And you are twice as big as the people hitting you. And they're not hitting you very hard."
Person 1: "ALL YOU DO IS SLANDER AND LIBEL. WHERE ARE YOUR VIDEOS? MY DOOR IS ALWAYS OPEN. I HELP VETERANS. WHAT HAVE YOU DONE FOR YOUR COMMUNITY?"
You see, no proof was given. No truth was discovered. But fallacies were committed. When confronted with truth, BS artists attempt to redirect. Since they cannot provide truth, redirection is the only course of action available. Snakeoil salesman gonna sell snakeoil.
Compare that with this example, where truth and proof are given:
Person 1: "Hey, look at me, I am protecting myself with qi power."
Person 2: "Interesting. But it just looks like physical conditioning + stage tricks. And you are twice as big as the people hitting you. And they're not hitting you very hard."
Person 1: "Sure, I have no problem showing some proof because I'm not a scammy salesman perpetuating myths to sell lies to people who want to develop mystic power. Here is another video of me using qi to protect myself. You can see this time that 1) I'm not flexing my abs to protect myself, 2) I'm blindfolded and don't know when the strikes are coming so I can't tense up at the last moment, 3) I'm not having people half my size hit me, and 4) the people hitting me are trained fighters who know how to punch."
Person 2: "Wow, good demo. You seem to have some legitimate qigong skill. Have you considered demonstrating this to James Randi? I think he would be interested."
Person 1: "Why yes. After all, if I demonstrate proof of mystic power, I would get the $1,000,000 prize. But since I'm not selfish, I would love to have that money to donate to charity or use for a good cause."
As CMA practitioners we will deal with a lot of BS on a regular basis. We need to always be promoting truth to help keep the woo out of our art.
