This article will address a couple of red-herrings often employed as rhetoric, rather than logic, in argument. So we can get back to logic.
1) “Something something, flying unicorns.”
- Here is a picture of a one-horned rhino being airlifted as part of a conservancy effort. It has nothing to do with our discussion. May we return to the topic at hand?
2) “So and so earned a Nobel Prize (or other comparable thing) and therefore knows better than you.”
- Yes, and Obama earned a Nobel Peace Prize. Your argument is invalid. Can we get back to the topic at hand?
