The website provides a venue for people to ask questions and people to answer questions regarding martial arts.
That seems to be happening just fine. No failure there.
Nothing states whether the most popular answers are true, or the most popular questions are good questions. Nothing forces querants to have to read or consider any answer that doesn't already fit their established world view.
It seems a little egotistical to demand the whole site shut down because the answers you like aren't the popular one.
If you want to find a site which will reaffirm your ideas about Qi - there's plenty of forums, plenty of communities around teachers who have books and DVDs and specific teachings.
I've spent a lot of years of my life pursuing traditional Chinese arts, as someone who is diasporan Chinese, it's not that this site has tossed away "thousands of years of Eastern wisdom", it's that a lot of our home cultures have scattered a lot of what was good between political persecution, destabilization and allowing hucksters to run roughshod over everything.
I've met a few folks who have done things which I can't explain with all the science I've studied, however - some of them freely admit they're not sure how some things worked, and they're generally not out there trying to sell books or convert everyone. Lumping in the people who specialize in parlor tricks like "Rub your eyes! Do you see lights? It's Qiiiii!" is a disservice and unethical.
A lot of us who are dismissing some of the claims are doing so because we've spent years trying many of these methods with a variety of folks.
And some of the effects we've gotten, between a few folks aren't consistently replicable. "I don't know why I can hold your neck and tell your ankle has been twisted years ago. I don't know why 3 out of 10 of us can do it and the others can't." There's not much of an answer to give when you say "Here's this anecdotal piece of evidence from an internet stranger that I can't prove to you, can't explain why it works, and I can't guarantee will work for you, good luck!"
At the end of the day, it doesn't matter whether anyone else believes it or not - it's a question of what you, personally can do with it. The best you can really get on a general internet Q&A site is recommendations towards books, sites, or schools to check out.
