How did you guess? ;)

I agree with you, and I like to think that most recons are intelligent enough to behave accordingly, but I also suspect that there are some who would rather deny new facts than change their ways. (As an example, though not exactly appropriate because they are not recons, the neopagans who still insist on believing in idyllic ancient matriarchal societies despite those theories being disproven.)
