By the way, that is Number One on Scott Adam's (of Dilbert) list of dumb Internet debating techniques.
I would counter by asking you if you feel empowered to ask anyone anywhere at any time for their ID? Is there anytime it would be "unreasonable" to ask for ID?
never heard of Scott Adam, so I didn't steal anything from him. I could suggest to add to add some techniques to his list, however. Certainly, as I have suggested here many times, there is reasonable and unreasonable, regarding the ID/search issue. It's written clearly in the law, what constitutes seizure, etc.
Using vague generalized questions to make a specific point, meaning arguing from the general to the specific should be on this highly prized list.
ie; ID checks are the equvalent of no ID checks in terms of potential success at identifying perpetrators, and all ID checks are the same in all circumstances.
