For what it's worth, I don't identify preoccupation with identifying fallacies, or with rhetorical classifications like "bulverism" or "steelmanning" with philosophy. At least, if you take a degree in philosophy I think you'll find that it's very much not like this. In my experience, this approach is much more characteristic of online forum argumentation, and subcultures like new atheism and rationalism. (Case in point: I mean "rationalism" in the LessWrong sense, not the Cartesian sense!) I agree with you that the style is irritating and superficial.
