It is fine to express a distaste for a growth hacker by what he or she does, seems silly to dislike them for their title.

I would say exactly the opposite. I expect the average HN reader has tremendous respect for what "growth hackers" DO. But I also think that a lot of the kickback against the term is the perception (justified or not) that it's an unnecessary, vacuous term that (ironically) is "just marketing". Or, IOW, a fluffy title that some people have adopted to make themselves sound more interesting.

If these folks were routinely being called Marketing Strategists or something, I doubt there would be all this discussion about it.
