If it was me that you were talking about, then I may have given the wrong impression or you took it.

Most of the time with most of my comments, people either don't respond or else they respond politely. Several times it has started very positive private discussion. Occasionally, however, people do react really badly.

Two factors that people should bear in mind though. I only downvote when I have see a specific good reason, and generally I think that the author can see the merit of the complaint as well. Secondly a small number of upset people can make themselves more heard than a large number of not upset people.
