If you consider my posts insulting, you should take a look at his posts with the insults aimed at me. Basically, he started this insult thing, I was just responding in kind. It seems that you prefer to see my unkind comments only, without paying attention to his. But I am a big boy now, so I do not complain about his tactics.
If you read one of my posts, you saw that I correctly guessed that Jay is a prominent figure here, you just confirmed that. Judging by the posts of some other members, they do have provenance here. Although I disagree with their point of view, I never accused them of pretending being expert in a field without actually being one. Foe example, one of them is a staunch defender of the Popper doctrine (I think you know my opinion about Popper), but I have no doubt that he is an experienced engineer, as he stated. You might be also
an expert in your field. at least I haven't seen any of your posts that go against common sense.
But Jay is different, none of his interpretations of mathematical statistics make any sense to me. You might disagree with me, but I suggest you ask him why he didn't present any reference to a material that supports his point of view. He could have laid this matter to the rest by responding to my multiple requests to provide any book or article giving some credibility to his assertions, but he steadfastly refused to do so.
You might still trust his mathematical judgment, but I do not think that majority of the audience agrees with you, although they might still like him
