I’ll violate my usual practice of not commenting explaining the reason for downvotes, to say this:
Preemptive comments of this type, which reflect the posters hostile prejudgement of the likely responses, are IMO, contrary to the letter and spirit of the HN guidelines including the rule of presumption of good faith, frequently (as in this case) involve preemptive violations of the guideline against commenting on downvotes, and contribute to a hostile atmosphere rather than productive debate.
If you are going to post something, with or without a disclaimer about your own background, do so without commenting about how you expect people to react in comments or votes. If there are responses you take issue with, take issue with them when they exist.
