It is common to believe that what sees is what must be seen by any person with vision, that one's own definition of a thing is the only definition, and that those who react differently to our own perceptions must be either mendacious or ignorant. From that standpoint, it is a crushing blow to find that half of the population of the US cannot see what is plainly before them.

Beware that feeling. Flip the coin, and that is just the problem your opponents have with you.
