Hmmm. So when I quote information from others, I am "passing it off as my own knowledge?".
With that logic, you can never state anything other than a personal feeling, lest you are trying to pass other's knowledge off as your own.
The funny thing is that you can't even successfully pass other's knowledge off as your own. Medical textbooks for over a century have said there are nerves in bone, and you got it wrong.
That's like stealing an empty money bag and thinking you are suddenly rich, despite looking into an empty space.
