Sub Tropes: More Straw Characters can be found at The Only Righteous Index of Fanatics! See Strawman U for an entire university composed of straw characters or Fictional Political Party for what can amount to an entire party of strawmen.

Cool." And then there was this guy who just doesn't seem to have very good manners.
While it's easy to see why the above scenarios didn't sit well with people, some of the concerns people express seem more, well, petty — if not entirely made up.
