You are correct. The only thing that could be a greater waste of time than
getting into a tit-for-tat semantic thumb-twiddling competition with this
contributor is to try to have a serious conversation with him.

So why do several people here constantly "waste their time" talking about me?

I am the first to recognize the things he does know
about aviation, and to post agreement when I actually do agree, but these
posts never elicit a response, and never go further, because he is not here to
share.

Typically, if I agree with someone, there's nothing to post ... since I agree.

It is a safe bet that this contributor is playing similar vindictive games on
other sites where professionals congregate, telling doctors, lawyers,
investors or other experts they do not know what they are talking about.

Vindictive games? I have no ax to grind. I just like aviation.
