The "other guy" is John Ousterhout, author of the Tcl scripting language.

Although I can see why you might consider him more "aggressive", I personally think it matters much more that he was, in general, far more descriptive of his reasoning.

Merely having an opinion is the easy part; being able to clearly articulate the reason(s) why one has a particular opinion is far more important, especially in this kind of conversation, and I in that regard I repeatedly found UB lacking.
