I think this is a clear story where conceptual clarity is both necessary and sorely lacking. It's unfortunate when academic disagreements degrade into accusations of racism, or when social awkwardness gets amped up into harassment charges, or when people file fake complaints in retaliation for writing articles they don't like. But beyond the emotional compulsion of the term "snitch", is there any reason to think that these are all facets of the same problem or that the same strategies would effectively handle all of them?
