I'm not saying (or thinking) that your decision to take up Salsa wasn't perfectly rational. What I do think is my decision not to do such a thing is also perfectly rational, which is probably why I had a negative emotional reaction to your very... vehement advocacy. In the case of archery, the structure of the discussion I gathered is: you said it was much inferior in health benefits to other activities - somebody brought up that it was simply fun - and you replied essentially that, well, then you should learn to find better things fun! That struck me as somewhat bizarre, because you were so forcefully condemning hobbies that were not optimal according to your metric without taking into account that other people may have other metrics and/or be constrained by various circumstances.

At this point, it's become pretty clear to me that the reason I voiced this objection was that I perceived you as arguing so vehemently that I felt essentially I was being told that I'm irrational because I like the wrong things.
