For one, is there anybody on earth who hasn't heard some of these stereotypes? That Hummers are rich boys toys, environmentally destructive, unattractive, completely unnecessary for driving on a paved road, not a real practical or protective vehicle in the war abroad (it can be blown to bits, could get a flat tire, engine might burn, run out of gas, you fill in the rest), and is considered by some to fulfill some odd longing unfilled void in a man's childhood?
In fact, there is an active war being fought: a war is between environmentally-friendly vehicles with more mpg than fun versus vehicles like the Hummer that just don't give a darn. In fact, if you'd recall, one of the famous battles occurred on a Hummer dealership where environmentalists vandalized a lot full of trucks.
