Gish Gallop

See more generally: Fallacy; Fallacies.
The Gish Gallop should not be confused with the argumentum ad nauseam, in which the same point is repeated many times. The Gish Gallop Fallacy quite overlaps with the tactic of an argumentative hydra.
"Sep 11, 2012 - Gish Gallop is a technique, named after the creationist Duane Gish
 who employed it, whereby someone argues a cause by hurling as many 
different half-truths and no-truths into a very short space of time so 
that their opponent cannot hope to combat each point in real time."
