I've seen a couple of diaries go through that brought up issues of when, if ever, we should fight rather than talk. As an overall theme, I'd like to point out that the arguments supporting not fighting rest on an underlying assumption: the people you are struggling against are sane. If this condition is met, then pacifism is the best strategy because rational empathetic people will reach a fair compromise.
Psychopaths and the delusional, however, must be fought - merely pointing out why their goals are unfair or irrational will have no effect on the final outcome. So let's see how this works in application...
In application, you have to do things like contact Ann Coulter's advertisers, as suggested by VolvoDrivingLiberal here.
Here's how it works: take your garden-variety psychopath such as Bill O'reilly. For his own egocentric reasons, he decides to delude his audience (which has more than its fair share of the delusional) into believing, say, that certain media members are unpatriotic (read: unsufficiently supportive of Republican behavior). After planting his delusion in their credulous heads, it is a simple matter to convince them to badger corporate advertisers whenever they say something that is "out of line." That sort of power brings in a lot of dollars.
Corporate advertisers don't like being badgered because it's costly. So they try to avoid the wrath of O'reilly and his gape-mouthed drones Bill Maher and Phil Donohue both ran into this. Maher (and Dinesh D'Souza) suggested that whatever their failings, it was incorrect to call the 9/11 hijackers cowards (a popular Republican meme). Donahue was forced to have two supporters of the administration on for every one administration critic he had on, and then had his program dropped despite respectable ratings. The network heads got calls from their advertisers wondering why they were supporting the terrorists.
These are just two examples of a pervasive issue: psychopaths intimidating decisionmakers for their own egocentric purposes. Let me make this clear here - the psychopathic and the delusional have the RIGHT to behave this way. They have the right to speak freely and contract with whomever they please. But, because they have these rights, we have a DUTY to provide a counterbalancing set of opinions to the decisionmakers.
If we call these advertisers, then they can point to our calls and apologetically tell the psychopaths that they can't give them special treatment any more. They need us to take the fire so that they can make the right decision - in this case, refusing to support Ann Coulter programming as long as it remains bigoted slander.
Perhaps you're worried about taking the fire, being branded a left-wing lefty liberal nutcase. Well, if you punch the bully in the nose then he might hit you back. But as a rule, bullies are soft in the guts. Once they realize you are ready to punch back then they work to avoid a fight. In their pathetic worlds, there's only one way to "earn respect"; the credible threat of negative consequences to them personally.
Perhaps you're worried that fighting back will make you "be like them." If so, you will be glad to know that fighting doesn't make you psychopathic or delusional. If you really don't want to be like them, then cultivate real empathy for your common man and rigorously test the beliefs you hold.
If we have learned anything over the last 15 years of Republican abuse, it is that if we don't fight the abusers then we are participating in the abuse.
