It depends on if you take the parent (err GGP) literally versus in context. My personal experience has been that people claiming that bias is unavoidable (alternatively that objectivity is impossible, or that everything is political, or ...) have usually been attempting to justify a reasoning process that supports a political or religious slant of one form or another.

A helpless "we couldn't possibly do anything about that issue" sort of mentality.

That said if we're talking literally then I fully agree with you that heuristics are a form of bias and can sometimes be a very good thing on a case by case basis.
