The facts should stand on their own. If one feels it necessary to take the facts and "dress them up", it most certainly devalues the argument when it comes out that someone's been telling half-truths.

Agreed. Hyperbole is something we all fall victim to sometimes, but it is something we should fight against. Be exact as possible, even if huuuge sounds better.
