In the context of the present poll, “logic” means those methods of reasoning that are guaranteed to produce, from true premises, only true conclusions. And the poll is asking whether classical logic is it.
I think you’re begging the question. I think you’ve given a definition of “classical logic” rather than “logic”.

I think that it seems that way only because classical logic has so definitively answered the question. The question is “how shall we reason?”, and it was not obvious beforehand that the first-order predicate calculus was the answer. It took two thousand years to get there from the ancient Greeks’ understanding.
