While that's all obviously true, I don't think getting his problem fixed was the intent of his comment. You're attacking the messenger of what appears to be a very common message.
It can be easy to ask in a way that implies you do not believe there are any.
A: "I looked up everywhere I could before coming to ask for help"
B: "You looked it up everywhere? Ok then, give me the name of at least one place you looked it up at."
Is there ever a negative connotation to asking for concrete examples? (I'd actually like a concrete example if there is one)
