Do incompetent people know they're incompetent? (Or, in Shakespearean terms, do shitheads know they're shitheads?) Do ideologues know they're ideologues?
Well, since only the shitheads and ideologues themselves can tell us, we'll never know for sure.
But we can be sure about the damage that the shitheads and ideologues do. In fact, we can even rate the damage according to a modified and adapted Fujita tornado scale.
The Conservative Incompetent/Ideologue Damage Scale
F0 Light damage, such as: n/a (damage always exceeds F0)
F1 Moderate damage, such as: rampant cronyism; breaches of separation clause; rollback of environmental regulations; immigration "reform"; punitive personal bankruptcy laws; frayed international relations
F2 Considerable damage, such as: diminished civil liberties; violations of international agreements; gaping holes in the social safety net; hyper–deficit spending
F3 Severe damage, such as: violations of due process guarantees; secret prisons; torture
F4 Devastating damage, such as: simultaneous wars in Afghanistan and Iraq
F5 Incredible damage, such as: simultaneous wars in Afghanistan, Iraq, and Syria (currently considered theoretical); incredible phenomena will occur
F6 Inconceivable damage, such as: simultaneous wars in Afghanistan, Iraq, Syria, and Iran (currently considered theoretical); inconceivable phenomena will occur
The Conservative Incompetent/Ideologue Damage Scale also can be used to assign ranks to individuals, starting with, say, John Bolton as an F1 and continuing on from there.
