Remember that, due to past unpleasant experiences, either to themselves or colleagues, many professionals have deliberately developed a perhaps unjustified, but understandable, technique towards ALL strangers:
Rather than detailing their objections to some particular hypothesis, they respond in a friendly manner in order to prevent potential stalkers from developing a hostile attitude.
I do NOT, in any way, consider yourself, due to your postings, to be a crackpot of potential stalkjing behaviour, but mention this in order that you'll take Dr. Schmidt's response as just that, the cautious, self-serving response to someone he simply CANNOT know who is, or whether you might pose some risk to himself or his immediates.
You'll need to look at Dr. Schmidt's subsequent scientific publications to see if you ACTUALLY made an impact on his professional views. He might well have been honest with you, but do not be disappointed if his articles does not seem influenced by the alternative hypotheses you transmitted to him in private e-mails.
