1) When "discussing" the Iraq War call anyone who disagrees with you a "chickenhawk."
2) Upon discovering that the person whom you just called a chickenhawk actually served in the military, change the definition of "chickenhawk" to include only those people curently serving in Iraq, who conveniently happen to be busy with other more pressing tasks to respond to your stupidity.
3) Establish your own bona fide entitlement to your stupid opinion on the topic, by proclaiming (after much evasion) that you did indeed "serve."
In the Peace Corps.
And joila. Congratulations, you are an official dipshit.
