The only way to check if it is someone's work then is to cross examine him. See if you can catch him contradicting what he wrote.
You've got to be kidding me.
I have tried to have a dialog with John W about his posts, and so have many other people. The minute anyone questions his posts, he turns into a crazy person.
The reason he does is very obvious; he copies-n-pastes other peoples work. That is why he always refuses to answer the questions. He refuses, because he can't.
If I copied an essay by a cardiologist on heart valves, and someone started asking me questions about heart valves, I wouldn't be able to answer.
That's what John does, and when he can't answer, he resorts to the same thing over and over again, which is to attack the person who asked the question.
John W has been caught red handed numerous times by myself and Andy C for copying-n-pasting (plagiarizing) other peoples work. Every time he has been caught the material was from a dispensational website.
However, this time is different. This time his post was put in the "subscribers post of the day" thread, and John went on to thank Mr. Deets, and told Mr. Deets that he would work on some more posts.
As "One in Christ" said, it is disingenuous. I agree with guyver, disingenuous is an understatement.
It's mind boggling to me how you and STP are defending John. MAD is so important to the two of you, that neither of you would ever tell another MADist they did something wrong in front of non-MADists. This is one of the reasons why people call MAD a cult.
