Dismissive statement

About
A dismissive statement is any statement which negates the value of an opposing argument without actually addressing any of its substance.

Although it is not actually a valid form of argument, it is frequently phrased in such a way that it might be mistaken for one; this usage is a form of rhetorical deception.

Argument by collective dismissal is an especially severe form of this, in which multiple points are dismissed as a group without any of them being addressed.

Varieties

 * argument from irrelevance: "I don't see how that's relevant." when the original argument has specifically named one or more points of relevance
 * argument from unimportance: "There are more important things to worry about."
 * argument by contradiction: "No, you're wrong." "I don't accept that hypothesis."
 * argument from overabundance: "You have too many points, I can't address them all." -- so I'm not going to address any of them.

Examples

 * "We don't find any persuasive, affirmative evidence that this is true.", when in fact evidence has been presented. (Philip Zelikow)

Query
Possibly this is a form of incomplete argument. Are there other types, or does "incomplete argument" generally boil down to "dismissal"?
