My point was that we ought to always examine who and why someone is designated an 'enemy', and whom it is claimed this 'enemy' opposes. Statements such as:

Will our enemies be inspired by our dissension? Probably, but that is the price we pay for having a democracy and freedom of speech.

already gives too much ground and credit to those doing the enemy designation and definition.

For example, of the many waring factions in Iraq, who do we think are in fact enemies of 'the United States', rather than a 'reaction against the occupation' or 'engaged in a power-struggle against other factions' or some other such thing. Whom among them actually give a damn of US domestic dissension considering the very real, local hell in which they are more immediately entangled?
