You should steel-man the argument. GP is talking about qualia, obviously for the sake of the argument you assume the comparison is between two people with similar eyes.
The steel men (armored enemy knights) are exactly the inverse of the straw man (training dummy) metaphor. I think it's a fantastic term since it directly addresses the point (tackle the best opposing arguments head on instead of a poor subset/facsimile of them), it fits within the existing straw man metaphor, it's terse, and it's very clear.
> The colors of traffic lights can be difficult for red–green color-blind people. This difficulty includes distinguishing red/amber lights from sodium street lamps, distinguishing green lights (closer to cyan) from white lights, and distinguishing red from amber lights, especially when there are no positional clues (see image).
> All but one admitted to difficulties with traffic signals, one admitted to a previously undeclared accident due to his colour blindness, and all but one offered suggestions for improving signal recognition. Nearly all reported confusion with street and signal lights, and confusion between the red and amber signals was common.
The wild success of traffic lights comes from having 3 colors at fixed positions. You put those 3 colors in a single color changing light and I would assume the accident rate would measurably increase.
