a. You said going on about downvotes, whereas I mentioned it only once, and you probably didn't bother to check whether the only other reference of the same kind was not made by me.
b. My actual comment and the replies I received (iow, the thread) were not off-topic if you had bothered to read them.
Comments that break the site guidelines in this way cross into offtopicness regardless of how relevantly they began.
