A more elementary perspective on the related issue:

Just because an object is determined not to be the colour orange, it is not logical to assume it must be blue - even though you prefer it to be. There are other possibilities to consider.

If one person, or a group, cant identify what the colour-shade is at that moment, it is illogical to say that this person, or group, does not have the capacity to identify the colour at some point in the future. It is alsoshallow thinking and unkind to suggest a whole group of people is, in some way, unprofessional, dishonest or biased because thay do not have an answer, but are working on it. I suspect you are not intending to suggest that, but are just very caught up (and possibly perplexed) by an argument that challenges what you hold as important.
